Schema validation

Hello there! I’m trying to get fastify-multipart form and fastify/ajv schema validation to work together in a restfull api. But I still get an error :

{
    "statusCode": 400,
    "error": "Bad Request",
    "message": "body should be object",
    "validation": [
        {
            "keyword": "type",
            "dataPath": "",
            "schemaPath": "#/type",
            "params": {
                "type": "object"
            },
            "message": "should be object"
        }
    ],
    "code": "BadRequest"
}

I’ve extented AJV with a fileType

ajv.addKeyword("isFileType", {
        compile: (schema, parent, it) => {
            // Change the schema type, as this is post validation it doesn't appear to error.
            (parent as any).type = "file";
            delete (parent as any).isFileType;
            return () => true;
        },
    });

Here is my schema

{
    "consumes": ["multipart/form-data"],
    "body": {
      "type": "object",
      "properties": {
       "urbanFile": {
          "isFileType": true,
          "type": "object"
        },
        "authorizationType": {
          "type": "string",
          "enum": [
            "buildingPermit",
            "planningPermit",
            "demolitionPermit"
          ]
        },
}

and here is my handler function

const mutliPart = request.multipart(
      function fileHandler(field, file, filename, encoding, mimetype) {
        console.log("file is in " + field + " and is named " + filename);
      },
      function done(error) {
        if (error) {
          throw error;
        }
      }
    );

    mutliPart.on('field', function (key, value) {
      console.log('form-data', key, value)
    })
    reply.status(201).send("Victory");

Is this a bug ? or am I doing something wrong? any help on this would be much much appreciated.

Cheers, Olivier

@chenchuraviteja what is your validation schema ?

[chenchuraviteja]

validation schema

schema: { tags: [{ name: ‘Category’ }], description: ‘Post category data’, consumes: [ “multipart/form-data” ], body: { type: ‘object’, properties: { name: { type: ‘string’ }, thumg_url: { isFileType: true, type: ‘object’ }, img_url: { isFileType: true, type: ‘object’ }, status: { type: ‘number’, enum: [0, 1], default: 1 } }, required: [‘name’, ‘thumg_url’, ‘img_url’] }, response: { 201: { type: ‘object’, properties: categoryProperties } } }
