Error parsing root-ca

I've substituded my certs in the .c file per the instructions (including \n\ at end of lines) but I'm getting a runtime error from the esp32 saying that it had an error parsing the root-ca. 

I have verified that the cert is correct, so that's not it. 

Here's the error:
`E (14239) aws_iot: failed!  mbedtls_x509_crt_parse returned -0x2180 while parsing root cert
`

Thanks!
