We are trying to run native build from a third party tool, the idea was to add certs on master branch in appcenter and run the native build (so that new branch will get the build config from master). But seems like it is not working as build fails with below error: [command]/usr/local/bin/openssl pkcs12 -in /Users/runner/runners/2.171.1/work/_temp/xxxxxx-xxxxx-xxxxx-xxxx -nokeys -passin pass: | /usr/local/bin/openssl x509 -noout -fingerprint -subject -dates Mac verify error: invalid password? unable to load certificate 4449422956:error:0906D06C:PEM routines:PEM_read_bio:no start line:pem_lib.c:697:Expecting: TRUSTED CERTIFICATE ##[warning]No P12 password was supplied. If the P12 file requires a password, the best practice is to supply it as pipeline variable and mark it secret by enabling the lock icon. ##[error]Error: /usr/local/bin/openssl failed with return code: 1 ##[section]Finishing: Install Apple certificate ##[section]Starting: Xcode build (signed) As a result we have go in to appcenter again and rerun the build after adding the passoword for .p12 file. Anyone faced this issue.
