ERR_OSSL_PEM_NO_START_LINE

[pankajjha]

Hi, I am getting this error on my callback function

Node: v16.19.1 @arendajaelu/nestjs-passport-apple: ^1.0.4 @nestjs/core: ^9.1.2

Getting Error: error:0909006C:PEM routines:get_name:no start line

Here's complete exception

}

Here's my Callback url function

@ApiExcludeEndpoint()
@Post('login/apple/redirect')
@UseGuards(AuthGuard("apple"))
async appleAuthRedirect(@Body() body, @Req() req, @Res() res) {
        try{
            console.log(req, body)
        } catch(e) {
            console.log(e)
        }
}

I found the problem

jwt.sign({}, this._key, {
    algorithm: 'ES256',
    keyid: this._keyID,
    expiresIn: this._clientSecretExpiry,
    issuer: this._teamID,
    audience: 'https://appleid.apple.com',
    subject: this._clientID
})

It seems jwt.sign function doesn't respect key file path and needs literal key

when I changed .env APPLE_KEYFILE_PATH from ./location/keyfile.p8 to "-----BEGIN PRIVATE KEY-----\nsdad...\nasda...\n-----END PRIVATE KEY----- it started to work just fine

login/apple/redirect remove @UseGuards(AuthGuard("apple")) work for me

...
@Post('login/apple/redirect')
async appleAuthRedirect(@Body() body, @Req() req, @Res() res) {
        try{
            console.log(req, body)
        } catch(e) {
            console.log(e)
        }
}
