PROVIDER_UNKNOWN_ERROR

The calendar provider returned an error that Pyas could not classify.

HTTP status: 502. Retrying the same request returns the same error.

What to do

Contact support and include the trace ID. Pyas is notified of every occurrence, and classifies or fixes each one.

Hint returned with the error: Retry the request once. If the error repeats, contact support and include the trace ID.

Why it happens

A provider error that Pyas has not seen before
