Goal: When using an OpenAPI specification of version 3.0.4 in Retool, the resource should correctly send requests with a body.
Steps:
- Set up an OpenAPI resource in Retool, referencing a specification using version 3.0.4.
- Ensure that the OpenAPI specification defines endpoints that require a request body (e.g.,
POSTorPUTrequests with a request body schema). - Attempt to send a request with a JSON payload.
- Observe that the resource sends no request body, and the
Content-Typeheader is not set.
Details:
- I have verified that the OpenAPI spec correctly defines the request body schema and works with other tools.
- The same API functions correctly in Postman and Curl, where the request body is included.
- I tested switching to OpenAPI 3.0.1, and the issue does not occur. I have not tested versions between 3.0.1 and 3.0.4.
- Retool does not display any errors, but the resource returns the following response
{
"status": 415,
"message": "",
"type": "https://tools.ietf.org/html/rfc9110#section-15.5.16",
"title": "Unsupported Media Type",
"traceId": "00-67c18176000000007202f1e27a9c0cc3-de838e925b2fe4ef-00"
}
This suggests that the API is rejecting the request due to the missing Content-Type and request body. I assume this is a bug with the OpenAPI resource in retool and the version 3.0.4
The logs confirm that the request is sent without a body and without a Content-Type header, leading to the API responding with a 415 Unsupported Media Type error.
- Screenshots:
I hope this helps resolving this issue. Let me know if you need additional information. Following a sample of the specification JSON:
