As an alternative, you can use the - wildcard character instead of the project ID:
projects/-/serviceAccounts/{EMAIL_ADDRESS}
projects/-/serviceAccounts/{UNIQUE_ID}
When possible, avoid using the - wildcard character, because it can cause response messages to contain misleading error codes. For example, if you try to access the service account projects/-/serviceAccounts/fake@example.com, which does not exist, the response contains an HTTP 403 Forbidden error instead of a 404 Not
Found error.
