query parameter defined as array of strings in Open API Specification does not work with comma separated values.

I have an API Specification designed in YAML using OAS 3.0.3. One field ex: customerId is defined as array of strings as below.

​

I want to pass comma separated values in the customerId field as part of query parameters. Ex: ?customerId='594918104','037833100','023135106'

​

That is the reason, style is set to "form" and explode to "false".

Reference from here: Describing Parameters (swagger.io)

​

name: customerId
	  in: query
	  description: Customer ID
	  required: false
	  schema:
		type: array
		items:
		  type: string
		  pattern: "^[A-Z0-9]+$"
		  minLength: 9
		  maxLength: 9 
		maxItems: 100
	  style: form
	  explode: false
	  example: ['594918104','037833100','023135106']

​

APIKit throws an error when I pass comma separated values in the customerId field. It works only if I repeat the query parameter name for each value. Same behavior when I test it using Mocking Service in Design Center.

ex: ?customerId=594918104&customerId=037833100&customerId=023135106

​

I do not want to repeat the key since the URL will get too long and it can potentially contain 100 values. That's why I am looking for passing the values with comma separated.

​

​Expected Behavior: ?customerId='594918104','037833100','023135106'

Appreciate for any help you can provide.
