Sorry to hear you’re running into this issue as well, @Matt844. Totally understand how frustrating that must be—especially since your Zap has been working for years without problems.
I’ve taken a look into the bug report that the Support team added you to and that seems a bit different to the error being discussed here. So I did some further digging and found a different bug report around authentication issues that result in a “Error from halted execution” error on OneDrive’s Upload File actions. So I’ve gone ahead and added you, and everyone else here that’s running into these errors, to that bug report.
As the Support team said, we’re not able to give a timeline on when you can expect a fix but we’ll definitely be in touch as soon as it’s sorted. And I’ll be sure to share any updates or workarounds I come across in the meantime. Really appreciate your patience on this while the team are working on getting this resolved.
Please do let me know if there’s anything else I can help with in the meantime.
