Question & Answer

I’m exporting p12 signing certificates from my local keychain and when I try to ‘Continue’ after adding the file, nothing happens and I see the 400 API error in the Chrome console.

{
    "error_msg": "Getting details of Certificate file failed."
}

Is what’s failing specifically an app store connect api endpoint? I am noticing errors with it recently, specifically around the devices endpoint but have seen a few other people having similar issues with others in the api.

I am having the same problem - I cannot upload a signing certificate in project settings > code signing

Update: I fixed the error - it was because I was exporting the private key itself from my keychain but instead I needed to go to “My certificates” and export the certificate itself as a .p12 file, which includes the private key.
