解析服务成功，beforeSave对某些用户返回“找不到对象”错误

Question

I have a mobile app which updates a Parse object by incrementing a numeric field. For a couple of users that update is returning an "Object Not Found" error result.

When looking at the server logs, I see a successful beforeSave for the object immediately followed by an indication of the "Object Not Found" error.

[32minfo[39m: beforeSave triggered for Timeslot for user Kd06Glks3q: Input: {... (truncated) Result: {"object":{"current":{"__op":"Increment","amount":1},"organizationId":"5KK3RckkmD","available":true}} className=Timeslot, triggerType=beforeSave, user=Kd06Glks3q [31merror[39m: Error generating response. ParseError { code: 101, message: 'Object not found.' } code=101, message=Object not found. [31merror[39m: Object not found. code=101, message=Object not found.

This only seems to happen with certain Parse users (2 so far). Other users performing the same operation succeed and the log shows the afterSave completing immediately after the beforeSave. I have set the VERBOSE environment variable to 1 but didn't see any additional data.

I am running Parse Server 2.7.4

Anyone seeing this type of issue?

Answer 1

It turns out that the object in question had an ACL that pointed to a missing Role object. I believe this lead to the Parse Server reporting "Object Not Found" error when it tried to apply the ACLs before actually saving the data. Would be nice if the Parse Error returned actually referenced the class and id of the object that was not found...
