Headers is not defined error ?

[tariq235]

Please guide how to use it ? I am unable to make it work. I have created .env file and added my api key but getting this error

@tariq235 I ran into the same issue on node 16, once I switched to node 18.15.0 and did a fresh install, everything worked.

I've tried everything and still receive header errors. I'm now on node 19.0
