Describe the problem/error/question
I’m trying to set up the Sentry integration in n8n with my self-hosted Sentry instance (not sentry.io), but I’m unable to run the workflow because it can’t connect to Sentry.
What is the error message (if any)?
Credential with ID "xxxxxx" does not exist for type "sentryIoApi".
Please share your workflow
(Workflow includes a Sentry node using a credential with a custom API URL pointing to my local Sentry instance.)
Share the output returned by the last node
The workflow fails immediately with the above error.
Information on your n8n setup
- n8n version: latest (Docker Compose)
- Database: default (SQLite)
- n8n EXECUTIONS_PROCESS setting: default
- Running n8n via: Docker Compose
- Operating system: Linux (local host)
Additional context:
- I tested the API key using
curl:- From inside the n8n container
- From the host
- From another network
- The API key works fine in all cases, so it’s not a network or auth issue.
- It seems like n8n isn’t saving or recognizing the credential correctly.
