Fix AstroActionError

✅ Solution

AstroActionError often arises when the expected request body format in an Astro endpoint (like `form` or `json`) doesn't match the actual content type sent by the client. To fix, ensure the client sends data with the correct `Content-Type` header (e.g., `application/x-www-form-urlencoded` for `form`, `application/json` for `json`) aligning with how your Astro endpoint is processing the request body; also verify the client is correctly formatting the data itself according to the selected `Content-Type`.
