Content & configuration

Example Swagger/OpenAPI definition:

          "name": "multipart-form",
          "in": "formData",
          "description": "One or more CSV files to upload.",

Describe the bug you're encountering

When you choose a file to upload, the UI mistakenly thinks that there is a validation error and will prevent execution of the request.

To reproduce...

Configure an operation parameter as shown in the JSON above.

Expected behavior

Choosing a file should allow the request to be executed. This problem is not present in Swagger UI version 3.24.3.
