it's a mixture of what language ts

for now mongoose on latest 5.9.20 version throwing a error:
Error loading script src/index.js in resource test: TypeError: firstLineError.stack.split is not a function stack: [object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object] Failed to load script src/index.js.

@d0p3t have you encountered such a problem or maybe you know how to solve it?
can you share your package.json?
