This issue has been reported by several users across different versions of Airbyte. The problem seems to be that the webhook test fails even when the webhook URL is valid. This issue has been reported on both the Airbyte forum and GitHub issues. In one of the [GitHub issues](
https://github.com/airbytehq/airbyte/issues/31902), a contributor suggested upgrading to Airbyte version 0.50.8 or newer to resolve this issue. If you're using an older version of Airbyte, you might want to consider upgrading. If you're already using version 0.50.8 or newer and still facing this issue, it would be helpful to provide more details about your setup (like your Airbyte version, deployment method, etc.) and any error messages or logs you're seeing. This will help in diagnosing the problem. If the issue persists, I would recommend reporting it on the [Airbyte GitHub](
https://github.com/airbytehq/airbyte/issues) or [Airbyte forum](
https://discuss.airbyte.io/), where the community and the Airbyte team can provide further assistance.
