Submit An Array of Integer Elements In formdata

Swagger sends the field location (array) as a single value

/signup: {
        post: {
          tags: ['Authentication'],

          requestBody: {
            required: true,
            content: {
              'multipart/form-data': {
                schema: {
                  type: 'object',
                  properties: {
                    ...schema.CreateUserBody.properties,
                    location: {
                      type: 'array',
                      items: {
                        type: 'integer'
                      },
                      example: [32.3046505, 30.6080822]
                    },
                    profileImg: {
                      type: 'string',
                      format: 'binary'
                    },
                  },

                }
              }
            }
          },
          responses: {
            201: {
              description: 'User Created',
              content: {
                'application/json': {
                  // schema:{
                  //   $ref: '#/components/schemas/User'
                  // }
                }
              }
            }
          }
        },
      }

i expected that the field(location) will be repeated for each element in the array

how would i make it work this way ?

I just ran into this bug as well. My case is with application/x-www-form-urlencoded. I think the issue is related to the requestBody section.

I am attaching an example where explode is set to true in both the parameter block and the requestBody and they behave differently.

The example midway down this page mentions that you can specify the explode param in the encoding block for the requestBody - https://swagger.io/docs/specification/describing-request-body/

I’m using that exact example, except setting explode to true.

@Crackz the next version of the spec, OpenAPI 3.1, will support exploded arrays in multipart/form-data requests, and this is the default serialization style for arrays in form data (i.e. style: form + explode: true).
