MediaWiki	1.25.1
PHP	5.4.16 (apache2handler)
MySQL	5.6.26

I get this error when I'm trying to use VisualEditor in Flow conversations:

[9149bd06] Exception Caught: Conversion from 'html' to 'wikitext' was requested, but core's Parser only supports 'wikitext' to 'html' conversion.

VisualEditor is working on other sites normally.

I have these lines in my LocalSettings.php:

$wgVisualEditorParsoidURL = 'http://localhost:8000';

$wgVisualEditorParsoidForwardCookies = true;

$wgSessionsInObjectCache = true;

$wgFlowContentFormat = 'html';

$wgFlowEditorList = array( 'visualeditor', 'none' );

Parsoid seems to depub html > wikitext without problems.

Can you tell how to fix this?

What version/git commit of Flow and core do you have?

In recent versions of Flow, you need to use $wgVirtualRestConfig (recommended, if it's mentioned in your Flow.php) or $wgFlowParsoid* variables (either the only way, or a deprecated but still-working way).

You can see https://git.wikimedia.org/blob/operations%2Fmediawiki-config/HEAD/wmf-config%2FCommonSettings.php (either for $wgVirtualRestConfig or history of that for the old way).

I'm using the latest version. I haven't defined $wgVirtualRestConfig in my LocalSettings.php and I cant find this from Flow.php. Flow parsoid configuration looks like this:

$wgFlowParsoidURL = null; // also see $wgVisualEditorParsoidURL

$wgFlowParsoidPrefix = null; // also see $wgVisualEditorParsoidPrefix

$wgFlowParsoidTimeout = null; // also see $wgVisualEditorParsoidTimeout

If i set $wgFlowParsoidURL = http://localhost:8000 i get an error: [c949daba] Exception Caught: Failed contacting Parsoid and neither editor is working in Flow conversations.

Flow-REL1_25-576f705

This is what logfile says:

FlowHooks::initFlowExtension: Warning: $wgFlowContentFormat was set to 'html', but you do not have Parsoid enabled.  Changing $wgFlowContentFormat to 'wikitext'

...and i've checked: Parsoid service is up and running. I even tested it on http://localhost:8000 and its working normally.

What do you have for all the $wgFlowParsoid... variables in your LocalSettings.php? You only mentioned one. They should all (well, one or two are optional) be set to the same as their equivalent VE one is/would be.

If you use IRC, joining us in #wikimedia-collaboration on Freenode may be faster.

require_once "$IP/extensions/VisualEditor/VisualEditor.php";

$wgVisualEditorParsoidURL = 'http://localhost:8000';

$wgVisualEditorParsoidForwardCookies = true;

$wgSessionsInObjectCache = true;

require_once "$IP/extensions/Flow/Flow.php";

$wgFlowContentFormat = 'html';

$wgFlowEditorList = array( 'visualeditor', 'none' );

#$wgFlowParsoidURL = 'http://localhost:8000';

$wgVirtualRestConfig['modules']['parsoid'] = array(

  'url' => 'http://localhost:8000',

  'domain' => 'localhost',

  'prefix' => 'localhost',

);

I also have defined namespaces but I didn't write those here. I haven't made changes to Flow.php or VisualEditor.php.

If $wgVirtualRestConfig is not mentioned in a comment in Flow.php, there is no need to set it for Flow's purposes, and it won't have any effect on Flow (other than maybe confusing people).

You should uncomment $wgFlowParsoidURL and also set $wgFlowParsoidPrefix, $wgFlowParsoidTimeout, and $wgFlowParsoidForwardCookies.

I think:

$wgFlowParsoidURL = 'http://localhost:8000';
$wgFlowParsoidPrefix = $wgDBname;
$wgFlowParsoidTimeout = 100;
$wgFlowParsoidForwardCookies = true;

should work.

You can raise the timeout if wanted/needed.

Hi

$wgVirtualRestConfig is not mentioned in Flow.php. Should I use these in LocalSettings.php or Flow.php?

$wgFlowParsoidURL = 'http://localhost:8000'; // also see $wgVisualEditorParsoidURL

$wgFlowParsoidPrefix = $wgDBname; // also see $wgVisualEditorParsoidPrefix

$wgFlowParsoidTimeout = 100; // also see $wgVisualEditorParsoidTimeout

$wgFlowParsoidForwardCookies = true;

If set these settings to LocalSettings.php and comment in Flow.php I get: "Due to a technical error, this post could not be retrieved." Failed connecting parsoid. Neither editor is working (WysiWYG, VE). If I do vice versa I get the same error. If I set these above setting to both files I get the same error.

Why does it fail if i use VisualEditor for e.g. new pages and can save those successfully. Ii can still access and see parsoid running at the server. I've restarted the service.

If i comment these setting in both of the files, WysiWYG wikitext editor is working but VE gives: Exception Caught: Conversion from 'html' to 'wikitext' was requested, but core's Parser only supports 'wikitext' to 'html' conversion.

My LocalSettings.php:

require_once "$IP/extensions/VisualEditor/VisualEditor.php";

$wgDefaultUserOptions['visualeditor-enable'] = 1;

$wgHiddenPrefs[] = 'visualeditor-enable';

$wgDefaultUserOptions['visualeditor-enable-experimental'] = 1;

$wgVisualEditorParsoidURL = 'http://localhost:8000';

$wgVisualEditorParsoidForwardCookies = true;

$wgSessionsInObjectCache = true;

require_once "$IP/extensions/Flow/Flow.php";

$wgNamespaceContentModels[NS_PROJECT_TALK] = CONTENT_MODEL_FLOW_BOARD;

$wgNamespaceContentModels[NS_USER_TALK] = CONTENT_MODEL_FLOW_BOARD;

$wgNamespaceContentModels[NS_CATEGORY_TALK] = CONTENT_MODEL_FLOW_BOARD;

$wgNamespaceContentModels[NS_USER] = CONTENT_MODEL_FLOW_BOARD;

$wgNamespaceContentModels[NS_TALK] = CONTENT_MODEL_FLOW_BOARD;

$wgFlowContentFormat = 'html';

$wgFlowEditorList = array( 'visualeditor', 'none' );

require_once "$IP/extensions/Echo/Echo.php";

If I add this to LocalSettings.php:

$wgVirtualRestConfig['modules']['parsoid'] = array(

 

'url' => 'http://localhost:8000',

 

'domain' => $wdDBname,

 

'prefix' => '100'

);

I get: [98970307] Exception Caught: Conversion from 'html' to 'wikitext' was requested, but core's Parser only supports 'wikitext' to 'html' conversion

I corrected this one in LocalSettings.php:

$wgVirtualRestConfig['modules']['parsoid'] = array(

 

'url' => 'http://localhost:8000',

 

'domain' => 'localhost',

 

'prefix' => 'localhost'

);

I also tested echo 'Foo' | node parse and it is working.

Log file still says: Warning: $wgFlowContentFormat was set to 'html', but you do not have Parsoid enabled.

$wgVirtualRestConfig is not going to work with your version of Flow. Please do not change or post that setting.

Never change settings in Flow.php (unless you're a developer working on Flow, but that's a different matter). Please change Flow.php back to the version you downloaded.

Add the lines I mentioned to LocalSettings.php ($wgFlowParsoidURL, $wgFlowParsoidPrefix, $wgFlowParsoidTimeout, $wgFlowParsoidForwardCookies).

After changing LocalSettings.php, retest. If it doesn't work, post your full LocalSettings.php.

> Why does it fail if i use VisualEditor for e.g. new pages and can save those successfully. Ii can still access and see parsoid running at the server. I've restarted the service.

Flow uses a different set of settings.

Hi, Flow.php restored from the original file. Changed settings as you described - not working: Failed to contact Parsoid. Here is the LocalSettings.php:

Im still fighting with this issue. Please Help.

Have you found a solution for this?

Was this issue with Flow not working with VisualEditor ever resolved?

When this issue is brought up again (see phab:T267407) folks seem to reference this thread.

But this thread only shows that the issue was never resolved, no?

OP's last message states that the recommended settings didn't fix the issue.

I'm also facing this issue and the recommend settings for $wgFlowParsoidURL, $wgFlowParsoidPrefix, $wgFlowParsoidTimeout, $wgFlowParsoidForwardCookies didn't resolve it.

I also created a new thread about this issue here:
