Asset Validation Failed (90034) Missing or Invalid signature

[williambuchanan2]

Hi all

I am trying to upload my Maui app to the Apple App Store from Azure Devops and running into a multitude of problems.

Currently I am getting this error:

Asset Validation Failed (90034) Missing or Invalid signature

I have create what I believe is all the required certs and provisioning profile so not really sure what I am missing. Here is what I have in my csproj file:

<PropertyGroup Condition="$(TargetFramework.Contains('-ios'))">
	<!--<RuntimeIdentifier>ios-arm64</RuntimeIdentifier>-->
	<CodesignEntitlement>Entitlements.plist</CodesignEntitlement>
	<CodesignKey>Apple Distribution: XXX PTY LTD (XXXXXAAU)</CodesignKey>
	<CodesignProvision>XXXProvisioningProfile</CodesignProvision>
</PropertyGroup>

I have the p12 file and the provisioning profile file in the Devops library, and bring them in to the build like this:

• task: InstallAppleCertificate@2
  displayName: 'Install Apple Certificate'
  inputs:
  certSecureFile: '$(appStoreCert)'
  certPwd: '$(CERTIFICATEPW)'
  keychain: 'temp'

• task: InstallAppleProvisioningProfile@1
  displayName: 'Install Apple Provisioning Profile'
  inputs:
  provisioningProfileLocation: 'secureFiles'
  provProfileSecureFile: '$(provFile)'

It just fails in Devops with no error messages, but on my mac I am using altool to verify the ipa file and it shows the error above as being the problem. Any thoughts?

Thanks
