ID 524411 - Nuke prints arrimxf_json_deserialize: invalid input to the terminal when reading raw ARRI Alexa 35 footage

UPDATE:

This issue was caused by ARRI camera's incorrectly writing metadata into their files. The metadata LensSqueezeFactor was written incorrectly for a short time, so if you have such a file where the metadata was incorrectly written, you will see the error.
