I can create credentials, but I can't select them in the nodes

[jmarcop]

Hello,

I’m new here, n8n looks amazing.

I have a problem with my credentials, that occurred with 2 different providers : Gmail & OpenAI.

I’m able to create the credentials, I see them in the credentials page, the green banner indicates the connection is okay

But then I can’t select them in the nodes. The credentials list is empty. I’ve tried to refresh my page, logout / login, delete the pod ( running on Kubernetes ).

What is the error message (if any)?

If I create the credentials through the node, the run fails with this error :
Node has no access to credential

Please share your workflow

Share the output returned by the last node

Hi @jmarcop

Thanks for posting here and welcome to the community!

It looks like the credentials you have created are not shared with the workflow.
Check that the workflow’s project has been shared in the credentials and/or that the owner of the credentials has shared them with you.

You can read more about credentials sharing in our docs

Hello Ria,

Thanks for you answer.

I’m running a self-hosted no plan instance, so I’m pretty limited with sharing feature.

I’ve made several tests and I wasn’t able to reproduice my problem

• Creating a workflow with the admin user => not visible by userB so not relevant here
• Creating a workflow with my userB :
  – I was able to create and use a credential
  – I was able to work in this workflow with my admin user, and to use the current credential, and create / use a new one

I don’t know how I’ve created the initial situation, but now everything is fine.

Thanks for your time
