My codes is from https://forum.step.esa.int/t/snaphu-read-error-due-to-non-ascii-unreadable-file/14374/3, which is similar to @luc and when I export files for Snaphu, I get the same IndexOutOfBoundsException exception in python3.6.9 Snappy package.
The exception occurs in SNAP 8 Snappy. The same code works fine in SNAP 6.0 Snappy.
I found the exception actually occurs in the code “ProductIO.writeProduct(product_snaphu, output_path, ‘Snaphu’)”, sometimes it won’t stop even the exception occurs, but then stopped when running “snaphu -f snaphu.conf Phase_ifg_*.snaphu.img 6341”, the error message is
“Unexpected or abnormal exit of child process 13076
Abort”
Grateful for any help!@ABraun
