Swagger Not allowed Values error on required definition

[PetroGromovo]

Hello,
I registered at swagger and created new app (api 3 version)
/tasks path has 2 not required fields and I can not set it not required,
it shows Not allowed Values error...

I have :

  openapi: 3.0.0

      title: VTasks
      version: v1

          operationId: tasks
          parameters:
            - name: page
              in: path
              description: The page number to be fetched. If missed default 1.
              required: true
              schema:
                type: integer
            - name: order_by
              in: path
              description: The order_by  be fetched. 
              required: false  // ERROR : should be equal to one of the allowed values allowedValues: true
              schema:
                type: string
            - name: filter
              in: path
              description: The filter for title field. 
              required: false // ERROR : should be equal to one of the allowed values allowedValues: true
              schema:
                type: string
          responses:
            '200':
              description: successful operation
            '400':
              description: Invalid tasks supplied
            '404':
              description: tasks were not found

But if to remove these required definitions, I got 2 errors :

should have required property 'required' missingProperty: required
Which is valid syntax ?

Thanks!

Are these parameters supposed to be path parameters or query parameters?

Path parameters (in: path) are part of the endpoint path, and as such must be indicated by {...} in the path template:

paths:
  /tasks/{page}/{order_by}/{filter}:

Path parameters are always required, i.e. they must have required: true.

Query parameters are send in the query string, e.g. /tasks?page=...&order_by=.... To use query parameters, change the parameter location to in: query.

Please see Describing Parameters to learn more about the parameter syntax.
