Additional context
Information about where the bug is happening:
None

Possible correction
If you have a possible solution to the bug, please describe it.
Intercept the error with the response "Fetching Post metadata failed" and remove such a post from the queue (mark it as "processed" and move it to the appropriate table), but in the statuses of the processing process reflect the error with a separate state (it is important not to lose the history, but at the same time do not try to download).

Screenshots
