Resume of change stream was not possible, as the resume point may no longer be in the oplog.

Hi,

For my mongodb source connect cluster was shut down last night. This morning upon restarting the connect cluster, one of my mongodb connector failed with error:

`Resume of change stream was not possible, as the resume point may no longer be in the oplog.`

As the documentation suggests, I removed the offset and restarted the connector. Yet I am getting the same error on restart.

Hi,

could you please share the startup log? It seems to me that offset removal was not done correctly and the old offset is still read.

Hi Jiri,

In the attached screenshot of Kafdrop, you can see that the offset was cleared. Check the last msg in kafdrop, it says EMPTY

Hi,

but the key is different, yo you have not overwritten the old one.
