      4. Add the function core_get_string to the service
      5. Create a token for the admin user for this service (copy this, we'll use it in a few steps' time)
      6. Go to the "Test the service" (the bottom option in web services overview)
      7. Set method = token, protocol = SOAP, function = core_get_string and click "Select"

      Soap protocol is broken in Moodle 4.2 because of a class rename. external_api was renamed to \core_external\external_api

      webservice/soap/locallib.php contains:

      external_api::set_timeout();

      should be:

      \core_external\external_api::set_timeout();

      Replication steps

      1. Enable web services (admin > adv. features)
      2. Enable SOAP (admin > server > webservices > overview > protocols)
      3. Create a new external service (don't use the mobile one)
      4. Add the method core_get_string to the service
      5. Create a token for the admin user for this service (copy this, we'll use it in a few steps' time)
      6. Go to the "Test the service" (the bottom option in web services overview)
      7. Set method = token, protocol = SOAP, function = core_get_string and click "Select"
      8. On the next page, set:
        Token: the token you created from admin
        stringid: error
        component: moodle
        lang: en
      9. Execute it
        Expected: You see "Error" returned.
        Actual: You see this:
