Problem getting a properly formed webhook URL
When configuring the extension and saving the Mailchimp API key, the webhook URL does NOT include my site details (https://mywebsite.com/) and begins with /mailchimpsync/batch-webhook/?secret=...). Thus, when using the "Add webhook" link on the Mailchimpsync Config page, the following error is returned:
{"type":"https://mailchimp.com/developer/marketing/docs/errors/","title":"Invalid Resource","status":400,"detail":"The resource submitted could not be validated. For field-specific details, see the 'errors' array.","instance":[REDACTED],"errors":[{"field":"url","message":"Webhooks are no good without a valid URL. Please enter one."}]}
It's not clear to me how to correct this error to get the webhook at Mailchimp created.
I can manually create a webhook in the Mailchimp app by pre-pending "https://mywebsite.com/wp-admin/admin.php?page=CiviCRM&q=civicrm%2Fa%2F#" to what is shown on the Config page, but the extension does not connect to it.
I am running CiviCRM 5.34.0 over WordPress 5.6.1 and version 1.1beta3 of the mailchimpsync extension.
