Harmony subset fails for some dates with error: 'NoneType' object has no attribute 'href'

[marceloandrioni]

Hello, I noticed that for some dates the download using the harmony subset option fails with the error 'NoneType' object has no attribute 'href'. But when I try to download the data without subseting, the download finishes without any problems, showing that the data exists.

Subset fails:

When downloading MUR SST data between 2010 and now, most of the subset failed attempts occurred between 2024-01-08 and 2024-07-24.

Thank you.

Hello, I am not sure what changed it, but now the only dates that fail the podaac-data-downloader subset are:

• 2021-02-20
• 2021-02-21
• 2022-11-09

The error message is the same:

podaac-data-downloader --verbose -c MUR-JPL-L4-GLOB-v4.1 -d /tmp --start-date 2021-02-20T08:00:00Z --end-date 2021-02-20T10:00:00Z -e .nc --subset -b=-54.0,-36.0,-31.0,7.0
ERROR:root:Error processing harmony subsetting request: WorkItem failed: nasa/harmony-opendap-subsetter:1.0.5: Subsetter failed with error: 'NoneType' object has no attribute 'href'

Also, as before, I made a test not using the subset option and everything worked fine, so the data is available. The problem is due to the subset.

Thank you.
