Attachment on Share point online access: 429 -Too many requests

Kinetic ERP

Version 2022.2 → 2024.2

We recently upgraded to Epicor 2024.2, and now users are periodically encountering a 429 – “Too Many Requests” error when adding attachments to records. Our attachment repository is SharePoint Online.

In earlier Epicor versions, we maintained folder structures to keep file counts below the 5,000-item limit. Since Epicor removed that restriction Erp11, we haven’t enforced the same structure.

Has anyone else experienced this 429 error with 2024, or have recommendations on how to resolve it? Do we have to go back to the 5,000 file limit?

I doubt file limits have anything to do with that error.

What would be good to know is if that error is actually passed back from sharepoint or if it’s an internal epicor error.

Either way, the endpoint is saying it’s getting hammered (or intentionally rate limited) according the whatever limits are set on that server.

Probably SharePoint 429 throttle due to epicor using a poor retry strategy.

If your m365 org is not likely doing more than 18k SharePoint requests per min or a user 3k per 5min then report it to epicare

Ask them to implement exponential backoff with jitter and let us know how it goes. :wink:

I had updated my open support case with Epicor. I will let you know response. Thanks for your time to review.

This is my guess to.

I’m just disapointed we didn’t get a ‘jitter-bug’ dad joke on this one from @Mark_Wonsil

I must have blown a circuit breaker. I’ll retry later. :person_shrugging:
