    Hi, I am sorry it could not help. For me what I have written above is what caused the issue. You may have a different issue then.

    You might need to investigate the error in browsers Developer Tools (F12). Usually it shows the error in console output or you can see the faulty request in Network tab. Then you would try to set breakpoints and analyze further. 

    Also you can try to contact Aras support.

Hi,

had same error on one of our custom Itemtypes, which was versionable as well.

Here is copy-paste of my issue description to Aras support:

The reason for this bug are RelationshipTypes, that do not have “source_id” set, which is the case of the “Workflow” RelationshipType. 

The source of the bug is the file “\Innovator\Client\Modules\metadata\itemType.ts”. There is a function “getItemType”, which causes the bug, because it does not handle “null” values (due to missing source_id).

Looking at this function in Aras version 12 SP18, one can see that there was a null check, so this bug was introduced in newer Aras versions.

 Add the null check back:

Here is the full function, with the bugfix (lines 5-7).

      Same issue here. The snippet above does not seem to resolve it, even after clearing browser cache. Any thoughts Alderaan ?
