Item CheckingIn event receiver

Question

---

I have a document library. When I upload a document and try to check in the same, I get the following error.

0x81072186 An event receiver has canceled the request.

Stack Trace:

[COMException (0x81072186): 0x81072186An event receiver has canceled the request.]

Can anyone please help?

Answer 1

It seems as if an Event Receiver has been added to the library or to the Content Type and that it for some reason rejects the checkin.

You can use SharePoint Manager to find out what/where the event receiver is.
