Unable to save content in latest build

Hi,

After the upgrade to build dev-4969 the save functionality stopped working. When I open an existing item and hit the save button, the following error appears in the network inspector:

The url for the item I am trying to save is: https://cms.erip.me/app/reasy-dev/content/content/75ddbce7-cff5-4009-8f1c-6118ea6e7928--ebf14446-f094-4cfb-bf83-3ec1b8cedd5f

It posts to: https://cms.erip.me/api/content/reasy-dev/content/75ddbce7-cff5-4009-8f1c-6118ea6e7928--ebf14446-f094-4cfb-bf83-3ec1b8cedd5f

The request payload is:

{"Title":{"en":"Legal","nl":null,"sv":null},"Subtitle":{"en":null,"nl":null,"sv":null},"Slug":{"en":"legal-notes","nl":null,"sv":null},"Body":{"en":"<p>Titel<br />Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque ....snip... odio sollicitudin in.","nl":null,"sv":null}}
{"type":"https://tools.ietf.org/html/rfc7231#section-6.5.4","title":"Not Found","status":404,"traceId":"|8f516b72-43ba3e74b2780fa9."}

I have…

  • [x] Checked the logs and have provided the logs if I found something suspicious there

I’m submitting a…

  • [x] Regression (a behavior that stopped working in a new release)

Current behavior

When saving content we get a 404

Expected behavior

It should save the content and give a success message

Minimal reproduction of the problem

Edit an existing content item, hit the same button

Environment

  • [x ] Self hosted with docker

Version: [squidex/squidex:dev-4969]

Browser:

  • [x] Chrome (desktop)

Can we keep this in the other thread. It is the same root cause.
