Just can’t create new credentials. Had no problems with that before.
Does only the testing not work or do the credentials actually also not work after you saved them and use with the node?
upd. Sorry, didn;t get you the first time. Despite the error, the creds are working
@jan Credentials I created earlier, work fine. The problem is to establish connection for the new ones. Another person asked me to help, and in my n8n account the problem was identical.
Thanks a lot for confirming.
That was a bug in credential testing for versioned nodes. It got fixed and will be released with the next version tomorrow.
As you realized. is really just the test not working. All credentials (new and old) will still work fine.
