Trigger won't restart, keeps getting suspended

I have a trigger which refuses to restart saying : “PlanExecutor error during aggregation :: caused by :: Resume of change stream was not possible, as the resume point may no longer be in the oplog.” … My trigger calls a realm function. The documentation says if it cant find it on the oplog it will just continue with what is in the oplog, but mine refuses to start. I cant see any switches that say ignore resume token … I’m relatively new to mongodb atlas so would appreciate some help … we’re using v5 of mongoDB.

I found the solution, restart in the realm UI has a tick box to say don’t use Resume Token.
