Hello! Awhile ago now, we ran into the Heroku buildpack problems that were causing our builds to fail. We eventually got that under control and everything is fine now!
But, during that time, we had many reverts that were happening at the same time. In fact, 8 reverts occurred while we were trying to fix our problem. What we found odd, and which is why I’m here, we had only one successful revert to a working version. Subsequent reverts failed. Is that expected?
So, the chain of events worked like this:
| Action | Version |
|---|---|
 Latest stable and working version |
v103 |
 New version tries to deploy, it fails |
v104 |
| Automatic revert to v103 succeeds |
v105 |
| Another new version tries to deploy, fails |
v106 |
| (Some other activity occurs, here, don’t exactly remember what it was) | |
| Automatic revert to v105 fails |
v109 |
| Then, like 109, all subsequent reverts try to go back to v105, which always fail |
In image form:
If that helps anyone or if I need to clarify anymore, let me know!
