Xcode Cloud: No signing certificate Mac Development

Hello, I am getting the following error in Xcode Cloud:

/Volumes/workspace/repository/macos/Runner.xcodeproj: error: No signing certificate "Mac Development" found: No "Mac Development" signing certificate matching team ID "22649D52Q5" with a private key was found. (in target 'Runner' from project 'Runner')

I have automatic signing turned on in Xcode and the program compiles/runs fine in Xcode.

Below is my ci_post_clone.sh script

#!/bin/sh

# Fail this script if any subcommand fails.
set -e

# The default execution directory of this script is the ci_scripts directory.
cd $CI_PRIMARY_REPOSITORY_PATH # change working directory to the root of your cloned (cloud) repo.
