sra_to_isatab_batch_convert from the develop branch does not work

[tbrittoborges]

I am testing the functionality from sra_to_isatab_batch_convert:

from isatools.net import sra2isatab

DEFAULT_SAXON_EXECUTABLE = '../saxon9he.jar'

zipped_bytes = sra2isatab.sra_to_isatab_batch_convert("ERP005654", DEFAULT_SAXON_EXECUTABLE)

Which outputs:

>> 2024-08-28 13:49:46,368 [INFO]: sra2isatab.py(sra_to_isatab_batch_convert:106) >> This function uses The Saxon XSLT XQuery Processor from Saxonica Limited (http://www.saxonica.com/)

Accordingly, the resulting zipped_bytes is empty: len(zipped_bytes.getvalue()) returns 0.
The saxon9he.jar, which is missing from the develop branch, was downloaded from the master
wget https://github.com/ISA-tools/isa-api/raw/develop/isatools/net/resources/saxon9/s axon9he.jar. I tested several other datasets, with the same error. I was using the develop branch, as the master does not with more recent software versions.
Any tips to get this working?
