Flutter: IPA build finds the GoogleService-Info.plist in folder A but it does not find it in folder B?

I have a pipeline that should build me 2 IPA files with different schemes and firebase connection but meanwhile the first type file built successfully:

The second throws this:

Xcode build done.                                           67.7s

As you can see the files in XCode can be seen:

It finds the file at Firebase/cicd but not at Firebase/uat.

This is the script I use to copy the file based on configuration:

if [ "${CONFIGURATION}" == "Debug-cicd" ] || [ "${CONFIGURATION}" == "Release-cicd" ]; then cp -r "${PROJECT_DIR}/Runner/Firebase/cicd/GoogleService-Info.plist" "${PROJECT_DIR}/Runner/GoogleService-Info.plist"
fi

if [ "${CONFIGURATION}" == "Debug-uat" ] || [ "${CONFIGURATION}" == "Release-uat" ]; then cp -r "${PROJECT_DIR}/Runner/Firebase/uat/GoogleService-Info.plist" "${PROJECT_DIR}/Runner/GoogleService-Info.plist"
fi

I wonder if anyone has any idea what could be the problem, what should I try to make it work?

Thanks in advance.
