Hello @DakshMiglani,

How did you solve your issue?

Yea, so I was running my emailing service on kubernetes which was also supplying it the sendgrid key via secrets, But I didn't realise that it was also adding a '\n' character to it.

That's why later, when I checked the sendgrid api key, it looked like:
"SG_SOME-KEY-HERE\n".

So I stripped that newline character and boom it started working.

That saved my day... have been searching the error for hours! thanks!

For me: In Vercel Environment Variables - hit Enter - add a \n to SENDGRID_API_KEY... lol

I think this is the issue I am having but not able to understand what do you mean by hit enter. and add a \n.
Could you please give an example of the value which is supposed to be passed in vercel.
Currently, my value for SENDGRID_API_KEY is something like in this pattern SG.part1.part2-part3
I am passing the value in vercel as this which is giving the error "SG.part1.part2-part3".
Could you please help how should I pass the value
The shown way to pass environment variable below in the pic is giving error.
