@rrmerugu — looks like several actions failed, but I think only you can fix this as the administrator.

https://github.com/invanalabs/graph-explorer/pull/58/checks?check_run_id=859752211 shows:

fatal: 'heroku' does not appear to be a git repository
fatal: Could not read from remote repository.

https://github.com/invanalabs/graph-explorer/actions/runs/165115922 shows:

Resource not accessible by integration

which suggests that this action doesn't have permissions to post a comment on the PR.

Can you take a look at these errors, please?

Appreciate the PRs @mbrukman .
Apparently there is a bug with "first interactions" Github action. This happens when the person creating the PR does not have permission to the repository actions/first-interaction#10 apache/airflow#7035. I think Deploy to Heroku must be similar issue.

Apparently the permission requirements for Github actions are not scalable for this usecase. I will look for alternatives to do the automation chores.

Meanwhile I will disable the Github actions and merge this PR
