Failed to add or update item. Index 6 out of bounds for length 6.
I upgraded ArcGIS Enterprise from 11.3 to 11.4. The 11.3 server had a custom experience builder widget as portal content prior to the upgrade that worked. After upgrading to 11.4, the same custom widget continued to work. In testing, we removed the custom widget and attempted to re-add it to the upgraded 11.4 environment and we got the following error:
In portaladmin, the log shows the following:
This puzzles me because it was working post-upgrade until I removed it and then could not add it back. I assumed it was a glitch in the upgrade so we completely reset the Windows PC and installed a new ArcGIS Enterprise 11.4 from scratch. Once that was up and running, we continue to get the same errors when attempting to add the custom experience builder widget from a manifest.json using the Add New.. Experience Builder Widget.
Has anyone else had this issue?
