[expo build:ios] Failed to generate Apple Distribution Certificate

I’m trying to build an iOS app by letting expo handle all the certificates, but it throws an error: “Failed to generate Apple Distribution Certificate” with this output:

Reason: Unexpected response, raw: {“responseId”:“97ee9ade-d713-4f52-b34f-695ab9a570e7”,“resultCode”:1200,“resultString”:“You are not allowed to perform this operation.

What can I do to successfully generate my build?

Looks obvious, have you tried following the instructions in the error? Mainly:

You are not allowed to perform this operation. Please check with one of your Team Admins, or, if you need further assistance, please contact Apple Developer Program Support.

I.e. you don’t have permissions to do this.
