InternalError: unconsistent stack size: 2 4 (pc=151) while starting plugin.

I have been working on a plugin and it was working perfectly fine. But now, when I try to run it the console shows this error:

InternalError: unconsistent stack size: 2 4 (pc=151)

I tried restarting thinking it might be something related to Figma’s internal behavior but didn’t help.

What might be the reason for this error?

Thanks!
