@saiskarur please post a short but complete JavaScript program that can be used to reproduce the problem.

Without haven seen code that can be used to reproduce the error, my best guess is that the program attempted to write to a GPIO that was configured as an input. Input GPIOs can not be written to, only output pins can be written to.

I'll go ahead and close the issue.
