Problem with snaphu export 'Metadata attribute MISSION not found'

Hi all! This is my first post on this forum. I couldn’t find any similar thread.

I have a problem with snaphu export feature. The point is when I try to export my TanDEM-X data there is an error: Metadata attribute ‘MISSION’ not found. Also, images that should be in my target folder are not generated properly. So I cannot go to the next processing step which is snaphu unwrapping etc.

This is what I did so far:

  1. subset
  2. interferogram formation
  3. multi looking
  4. filtering

I already did phase unwrapping in SNAP and everything was working correctly some weeks ago. I also tried to update my software and even reinstall it a couple of times. Any ideas on what else can I do?

Dear @ABraun She is my student and mentioned that she has problem with SNAP. So, if you know the reason for this problem, I would be thankful that you or other members of this forum help her.

I have seen the error report, but I don’t know the answer, sorry.
