I have developed a script for after effects and i was testing it in after effects cc 2019 and everything looks perfect however when i tired to run the script from the ScriptUI folder in after effects cc 2018 i got a random error from the internal adobe code.

Just for records, the script was working fine in after effects cc 2018 but for some reason when AE bugged out and i forced it to quit from the task manager i started getting this error

Code Error in Extendscript Debugger

Do you have a try/catch block in your code that deals with exceptions?

From what I can tell looking at the code is that it throws SyntaxError() function, but there's no catch statement to actually catch it.

Thank you Thomas for the tip but the problem is that this abort function belong to Adobe extendscript internal code not the one i wrote.

And it only occurs in After effects CC2018 and below! because the AE2019 is working fine.

What do you mean by "Adobe extendscript internal code"?

In your screenshot I can see that the code that throws the error has something to do with parsing JSON.

Are you parsing JSON data in your app and if so, did you make sure to add your own implementation of a json parser?

See this tutorial for details:

Thanks Mathias! I i have fixed this issue by rechecking my json file which is the responsible for this error! there was a strange bits of characters like so \ufeff that made the parse to fail (the program coudlnt figure out what type of escaping is that) and i dont know who added that lol so after i deleted that i got everything working fine

[{"proxyData":{"proxySourceFileName":"0000216F.mp4","proxyFormatId":557,"proxySuAlias":[],"proxySourceFilePath":"\\dev-lala\dp1\video"},"hrData":{"originalSuId":23,"isPathChanged":false,"originalSourceFileName":"00002163.mxf","originalSuAlias":"m:\hires","originalSourceFilePath":"m:\hires","originalFormatId":"599"},"Id":"4688"}]
