| - I don't have permissions to update this PR. To update your fork with upstream using bot you need to to enable [Allow edits from maintainers](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/working-with-forks/allowing-changes-to-a-pull-request-branch-created-from-a-fork) option in the PR. | |
| - Another possible reason for failure can due to the fork being in an organisation and not under a user. | |
| - The fork is located in an organization, not under your personal profile. | |
| - There is a conflict in the PR. Please resolve the conflict and try again.`; | |
