When triaging, make sure to identify whether this issue should or shouldn't be happening -- if it's not truly exceptional, try to convert to a less interesting tracing method (e.g. a warning trace).

Is really difficult to determine where is this bug originated, the exceptions does not have an operation_id so I couldn't find a request that failed.

by looking at the code I am assuming that this is happening in the method upset of the attachmentStore file that have something like

so if the token has some invalid characters we could have this problem.

More investigation and better logging is going to be needed in order to prove identify the issue
