Error Message

Describe the problem/error/question

I'm not able to view n8n version history for my workflow. When I try, the version history pops up for a second (at least when it's empty), but is then replaced by an error about "listing all users".

What is the error message (if any)?

Error message: Not applicable — I can reproduce this error without executing the workflow. I have also tried executing it first but that doesn't fix the version history.

Describe the problem/error/question

I'm not able to view n8n version history for my workflow. When I try, the version history pops up for a second (at least when it's empty), but is then replaced by an error about "listing all users".

What is the error message (if any)?

(x) Version History

Listing all users is limited to instance administrators. Filter by project to list project members.

extent analysis

TL;DR

The error message suggests that the issue is related to user permissions, and filtering by project might resolve the "listing all users" error when viewing workflow version history.

Guidance

  • The error message indicates that listing all users is limited to instance administrators, so checking the current user's role and permissions might be necessary.
  • Filtering by project, as suggested in the error message, could be a potential workaround to view version history.
  • Verifying the workflow's project settings and ensuring that the user has the necessary permissions to view version history might help resolve the issue.
  • Checking the n8n documentation or enterprise license features related to user management and permissions might provide more insight into resolving the issue.

Notes

The provided workflow and debug information do not seem to be directly related to the error message, so focusing on user permissions and project settings might be a more productive approach.

Recommendation

Apply workaround: Filter by project to list project members, as this might allow viewing version history without requiring instance administrator permissions.
