SEVERE: org.esa.s1tbx.io.sentinel1.Sentinel1Level1Directory: cannot read tiff inside slc zip

Hello, I have created a script to process sentinel-1 data using SNAP GPT, before November 2023 no problems arise when this script run. But when I started running this script in 2024 the following error appeared:

Executing processing graph

here is the snippet of the script I wrote in SNAP GPT:

....

the error appear before apply orbit, so I think the problem in process TOPSAR Split, I have no idea what is happening, is anyone experienced the same things?

thanks

Thank you for reporting this issue.
Jira ticket SNAP-3604 created.

Can you try to run the graph on the unzipped product?

Hey Diana,

I had the same problem. I can confirm that running a graph on these two unzipped products works, whereas it did not work on their zipped counterparts:
S1A_IW_SLC__1SDV_20231224T175424_20231224T175451_051800_0641CF_AFBF.SAFE and S1A_IW_SLC__1SDV_20240105T175423_20240105T175451_051975_0647CE_4152.SAFE

For context, this is my graph, apologies for the full XML, I am unsure where is best to snippet:

Hi there

I am also having the same problem with files downloaded after 20230930.

Is there any solution coming soon?

Cheers,
Ng

Hey guys, I too am getting this issue, any process that involves 2 slc’s of 4 GB or so in size, still works fine, however, the newer 7 GB SLC files are showing this issue, any help will be helpful.

Best Regards
