No annotation xml file found error when processing with ISCE

I am getting an error when downloading using burst2stack. The same dataset works fine when starting with the regular SLCs.

When I run the first the first ISCE processing step I get an No annotation xml file found error:

Any idea what is happening? I downloaded the data using:

burst2stack --rel-orbit 127 --start-date 2024-01-01 --end-date 2024-03-31 --extent 110.39 -7.6 110.49 -7.49

I also encountered a similar problem. The swath number is 2 when generating configs for stackSentinel. But the annotation xml in .SAFE is for swath 1. I solved this issue by unifying the input swath number for stackSentinel and the s1a-iw{swath_num}*.xml.

Can you please be a bit more specific on how you solved it? What do you mean with unifying? Which files did you edit manually?

The swath number explicitly specified in your config_reference is [iw2], but the provided xml in .SAFE is iw1, which makes the problem in validating the input .xml.

Change the swaths_number in config/config_reference, or specify the swath number when calling stackSentinel.py can solve this, --swath_num.

Another option may just use the default '--swath_num', '1 2 3'.
