We have a page within our site that is receiving the following error message when we try to save from within the CMS:
'Failed to persist entry: API_ERROR: Validation Failed'.
This only seems to be happening on one of the pages within our site.
Additionally, we are seeing this message when we first attempt edit the page:
Netlify CMS is adding labels to 1 of your Editorial Workflow entries. The "Workflow" tab will be unavailable during this migration. You may use other areas of the CMS during this time. Note that closing the CMS will pause the migration.
I am getting this on one of my posts in a project as well, but only seems to affect one post and can’t tell why. Sadly, the support guide you listed @hrishikesh does not address the Validation Failed error.
Sorry for the delay here. Are you still encountering this issue? If so, can you please share a link to your site as well as the shortcode on the other posts that are not having the same error? Thank you!
FWIW I removed these regular expressions but I still got the alert message listed above whenever I have posts waiting in the workflow queue, but when the posts are approved and deployed then I no longer get the message. Not sure if that is an alert that there are posts waiting, but if so it’s not a very clear alert, bad UX for CMS users, but doesn’t break functionality entirely.
