SciSnap! is one of my favorite libraries because it allows me to do literally twice as many things than without it. But I hate this specific issue in the BLOB reader block:
Going back to the SciSnap! JS I searched for the function and lo and behold, ide is not defined or declared in the function. The only way this block works is if it's a TEXT, JSON, etc but not any other file because the error is coming up when the function is trying to warn the uploader about the file type. This is an easy fix, hope to see this fixed soon
