iOS deployment - Github Actions pipeline failing due to code signing error in Pod target

I'm very new to Github actions. Any help would be appreciated.My iOS project has ReactNative frameworks added via Pods. It's working fine when building locally in XCode.But in github actions for app deployment, getting below signing error for pods target.

/ios/Pods/Pods.xcodeproj: error: No signing certificate "iOS Development" found: No "iOS Development" signing certificate matching team ID "**" with a private key was found. (in target 'React-Core-RCTI18nStrings' from project 'Pods')

/ios/Pods/Pods.xcodeproj: error: No signing certificate "iOS Development" found: No "iOS Development" signing certificate matching team ID "**" with a private key was found. (in target 'RNCAsyncStorage-RNCAsyncStorage_resources' from project 'Pods')

I've added post install script in Podfile as below

By setting this, I am expecting Pods target will do 'automatic' signing from the given teamID in Pipeline deployment.I've tried setting 'Manual' signing in Podfile, but that also giving the same error.

Below shows the signing for Pod target.

Pod - Signing

Any help would be appreciated.
