Hi @CaptainHoangLe,

Seems like the code in master is the same, at least around this function, though I cannot reproduce with the default dashboards.
Looking at this error, seems like it happens if the request is malformed, specially around the headers.
Can you post the curl request made for it here? (or a sample that can be reproduced)
Can you also test against the code in master?

Thanks!
