AssetDatabase.LoadAssetAtPath<TextAsset> returns null for JS file in Unity 2021.2.19f1

We have a PostBuild script that loads the js file as TextAsset
We have been having this script since version 2019.2.18f1 and had no issue Loading the js file as TextAsset
But when we updated the version to 2021.2.19f1 the LoadAssetAtPath for js file returns null.
But the function LoadAssetAtPath works fine without any issue for the html file type.
The js files loaded are all present in the Project Assets folder.

 

EDIT: disregard my mad ramblings below: I realize you're talking about an editor-time change... I thought you were speaking of final bundling build rules. You might still try renaming it just to see if that's what is in play, and possibly file a bug if it is.

disregard:

It's possible that a change to Unity's bundling rules now excludes ALL "source code" files.

This might be simply to preclude inadvertent data leaks of source code.

I know if you drop scripts into a

Resources

directory, the files are NOT included.

You could test this instantly just by duping the file, renaming it as TXT file, connecting it and seeing if it works.

 

Yes its confirmed

TextAsset testtxt = AssetDatabase.LoadAssetAtPath<TextAsset>("Assets/PostBuild/test.txt");
TextAsset testtxtjs = AssetDatabase.LoadAssetAtPath<TextAsset>("Assets/PostBuild/test.js");
both the above files are present in the PostBuild script and the first one returns the text in test.txt
whereas the test.js returns NULL.
I will file a bug.

Thanks

 

An alternate solution to this that I am currently using since the js file wont load in Unity 2021.2.19f1(which is the version I am currently using)
File.ReadAllBytes and converting the byte array to string.
