环境变量不会用 javascript 中的新行替换 '\n' 并抛出错误：0909006C:PEMroutines:get_name:no start line

Question

I connected to my gmail account with google api using service account. while doing this, I got credentionals in .json file with 'private_key', looks something like:

-----BEGIN PRIVATE KEY----- MIIEvQIBADANBgkqhkiG9w0BAQEFAASCBKcwggSjAgEAAoIBAQCfE0lFOu6odsZd vqCrXHbyFvalkMReFi1bo76tjSpNuJkDlHRKlx0ro+VZ0bqifIbo3yRGST+/Bxyr

now, I have to deploy my app, so I added the private_key to .env ,

unfortunatly I get this error: Error: error:0909006C:PEM routines:get_name:no start line .

when console.log the proccess.env.private_key , I get it like this:

-----BEGIN PRIVATE KEY-----\nMIIEvAIBADANBgkqhkiG9w0BAQEFAASCBKYwggSiAgEAAoIBAQCupQiD7fphkibb\nSRJ9x7tJLLWPvL+abF7pUsM30dwSxLtws4O83SFfDnRT9SYebZGz+9EVkv4VtSux\nzOhmLIBc3zUIAQyaD9VZFnZKFf5B0fjD/fp4Oq+AWXtMy

in one long line... and all the \n is still there instead of being replaced by a new line.

Answer 1

       let privateKey =  process.env.PRIVATE_KEY.replace(/\\n/gm, '\n')

this regex replace the \n to brake line.
