This isn't working on my server on SwaggerUI and SwaggerEditor. Another thing, I have several paths & methods. All are working (GET, POST, PUT, DELETE with json). Only this one with content-Type multipar/form-data doesn't work on my server. I suspect it may has to do with some permissions (no file upload allowed). If so I'm not sure which folder should be opened on SwaggerUI. swagger multipart TypeError: Failed to fetch Hello, I have a swagger installed on IIS Windows Server 2016. It is linked with ServiceNow. I have several paths and methods working fine except this single one. It is using a multipart request body. I get an error "TypeError: Failed to fetch" I have tried the code on the swaggerHub and it worked; I suspect something is missing on my IIS or on my swagger UI config. Do you have any clue? post: parameters: - name: "Content-Type" in: "header" required: true schema : type : "string" default: "multipart/form-data" requestBody: content: multipart/form-data: schema: type: "object" properties: table_name: type: 'string' format: 'string' example : "rm_feature" table_sys_id: type: 'string' format: 'string' example : "6e1ef1f41bd9bf4421d44111cd4bcb2f" data: type: "string" format: "binary"
