Cannot create qr

[Tsjippy]

Thank you for this great package.

I have installed it on a rpi3b. I access it fro a winows 11 machine

This command http://192.168.0.202:3000/session/start/test runs fine.

But this command http://192.168.0.202:3000/session/qr/test leads to the following error:

 npm run start

> whatsapp-web-api@1.0.0 start
> node server.js

I think the browser is not able to start due to architecture of your board. Try to install it from your repository and point the CHROME_BIN env to the executable.

[Tsjippy]

thanks for the quick reply.

That at least changed things.

If I run the url http://192.168.0.202:3000/session/qr/test again this is what I get:{"success":false,"error":"Session already exists for: test"}

[avoylenko]

@Tsjippy the ERR_HTTP_HEADERS_SENT error has been fixed and awaits @chrishubert approve

[Tsjippy]

Thank you.

for now I will just runs the thing on my laptop and copy the session folder to my rpi. See if that works
