error while executing the command "node node_modules/gmail-tester/init.js credentials.json token.json testAlias@gmail.com"

I am trying to use gmail-tester, I have downloaded the credentials.json following the steps indicated in the documentation, but when I run the command, the tokenjson is not created and the error comes out:

---

never asks to enter the code, the url takes me to the code site, but it does not leave where to put it, credentials.json file are located in cypress root folder, cypress version 12.4.1.

Can anyone help me what I’m doing wrong?
thank you.

Looks like you're running a server on port 80. Try stopping it while running init.js.

I'm having a similar issue, but my port is not already in use, i have just permission denied 0.0.0.0:80.

Node.js v18.13.0

Simply can be fixed when executing the init.js-command as sudo -> see this or workaround

I am facing similar issue where it doesn't ask me to enter the code, however I am not seeing any errors. Initially I set up this on a laptop and I got a new laptop, then setup all the required tools on my new laptop it doesn't ask me to enter the code on my new laptop.

cypress - 10.11.0
NodeJS - 16.13.0

Could someone please help me here

I was able to figure this out, by removing this "urn:ietf:wg:oauth:2.0:oob" value from redirect_uris array from my credentials.json file and only have "http://localhost", then try generating the token. With this there will not be the step to paste the token from the browser to terminal, instead once the command for token generation is ran there will be a message "gmail Found" and gmail_token.json file (or whatever the filename is put while token generation) is generated.

Running something on port 80 usually requires root level access, so you can either run it with sudo or grant low-numbered port access to Node:

sudo setcap CAP_NET_BIND_SERVICE=+eip /usr/bin/node

(Once gmail-tester generates a local token file, sudo is not required).
