When i changed token lifespan from 2.weeks(default) to 8.hours I started to get this error. I fixed it by removing old token, after this everything is working. I don't think that this behavior is correct

[anjoseb121]

It just happened the same error in my project

[gen1321]

If I make a pr on this will u accept it?

[TomasBarry]

I was just about to create an issue about this - Any value under 11 days (I've attempted 263 hours which is one hour less than 11 days) results in the exact same issue.

Here is an issue where it is also referenced (but as part of a different issue).

Update

I've discovered that the issue seems to have to do with already existing tokens.

I've not been able to consistently re-create the issue but I have been able to (seemingly) get rid of the issue by removing all tokens for the user:

user.tokens = {}
user.save!

This being the line where the issue is raised I believe this issue is to do with the fact that the entry for some tokens[client_id] has already been removed and we're calling build_auth_header with an already deleted/removed client_id.

@lynndylanhurley, have you any thoughts on this?

[Arielicoms]

Hi, I had the same issue about nil class but I had to call a different method, I did it with create_token

[djarkobobanov]

user.tokens = {}

Hi Tomas, can i know on which files did you alter the user.tokens = {} ?

[TomasBarry]

I didn't do it in a specific file, rather in the console while debugging to verify that it fixed the issue.
