Error with JSON Parsing and Undefined Property Access When Unminifying JavaScript with Humanify

[abdurrahim11]

I am facing problem while running one of my big script first everything is fine then after some time it gives below error

my minify js link: https://drive.google.com/file/d/1QHHRw_YKbYwgf7rbT8R8qP6Uh5BxNZ4l/view?usp=sharing

SyntaxError: Unexpected token '.', ..."E" },

This is very probably the same issue as #12

[0xdevalias]

Potentially related:

• Unexpected token : in JSON at position 426 #12
• Expected ',' or '}' after property value in JSON at position 2262 #17
• Script process is running for hours but never calls OpenAI API #18

[jehna]

This should now be fixed in v2 since there's the long awaited JSON mode with the new structured outputs. Please take a look and repoen if anything comes up

@jehna Thanks a lot for providing that tool!!

I using humanify 2.1.2 but still face the issue.

code: 'BABEL_PARSE_ERROR',
reasonCode: 'UnexpectedToken',

@tkreuder I'm not 100%, but I believe this may be a separate issue to the above. It sounds like the error is happening during the babel parsing of the code, not the JSON parsing. To debug it further, I suspect the code you're trying to to unminify will be needed (or at the very least, tracking down what part of the code is being referenced there as being unexpected. Given it's happening in the babel area of things, there's also a chance that this may be a bug/unsupported edge case in webcrack (which this tool uses for unminification)
