How I can sign jwt accesstoken in node using typescript

I want to sign an jwt accestoken, when the user gets logged in. I done this before without typescript like this:

 const accessToken = jwt.sign(
            {id: user!._id,

I setted the both exclamation marks for telling typescript that the values cannot be null. But it underlines me process.env.JWT_SEC and tells me:

No overload matches this call.
The overload 1 of 3 (payload: string | object | Buffer, secretOrPrivateKey: Secret, options?: SignOptions | undefined): string) caused the following error.
The string | argument undefined" cannot be assigned to the Secret parameter.

Thank you for your help.
