Greetings! According to CommandLineTool v1.2 ChangeLog: - When using `loadContents` it now must fail when attempting to load a file greater than 64 KiB instead of silently truncating the data. However it looks like v1.0 or v1.1 also fail when loadContents for large files instead of silently truncating. Am I missing something? I am using cwl-runner 3.0.20201203173111 for testing. Thank you for your time in advance. I am trying to decide whether to revisit my previous v1.0 tools since they are written without concerning file size. ---

Hi @green555, Can you provide a reproducible example that shows the error that you’re seeing? Alexis ---

Hello @green555 We decided to make cwltool more conservative even for CWL v1.0 and v1.1, as an exception was decided to be better than silently truncating too-large files.
