@sgoggins I remember during our meeting this week or last that you mentioned some additional context to this error. Would you be able to provide that here incase it is enough for someone on my team to take this issue on?

[cdolfi]

@sgoggins bumping question

[sgoggins]

@IsaacMilarky added some additional logging. This is a celery error and we are sorting down the stack.

[cdolfi]

@sgoggins got it, thanks! If an issue pops up that you think would be good for @EngCaioFonseca to work on send it my way

[MoralCode]

This exception stack trace doesnt seem to touch any augur code (all the lines in the exception trace are in site-packages)

is this still an issue?

[cdolfi]

will reopen if I see it again
