Hello,
I recently had some issues with n8n and had to reinstall, I was able to export my workflows but not my credentials. After installing the latest version of n8n and importing my old workflows, I am unable to use a connection that I was previously using. It is a graphql node and the error I am getting is
I have the same credentials in a postman workspace and am able to get a token using OAuth 2.0 just fine, I tried recreating the workflow from scratch and am still getting the same error.
Information on your n8n setup
n8n version: 0.211.2
Database you’re using (default: SQLite):SQLite
Running n8n with the execution process [own(default), main]:main
Running n8n via [Docker, npm, n8n.cloud, desktop app]:Docker
Hi @Matthew_Gomes, can you try re-creating the credentials from scratch you are using in your workflow? I wonder if this might simply be a case of your new instance using a different encryption key for credentials.
Apologies for the late response, I tried recreating the credentials and the same issue occurs. I thought it may have been the fact that I went from the ‘n8nio/n8n:latest-debian’ image to ‘n8nio/n8n:latest’ so I tried again with the ‘n8nio/n8n:latest-debian’ image and it still did not work, recreated the credentials after changing images. This issue has me stumped.
Which Grant Type are you using? A bug came up recently with the Client Credentials option which I put in a fix for a couple of days ago that will be in the next release so I am wondering if maybe it is that.
If you are using Authorization Code it could be something else.
Hi @Matthew_Gomes, @Jon’s fix has been released with [email protected] which is now available. Could you give this a quick go and confirm if you are still having trouble?
