An error occurs when a parameter schema contains a non-string const

[frozenbonito]

An error occurs when a parameter schema contains a const value that is not a string, as shown below:

openapi: 3.1.0
info:
  title: Example API
  version: 1.0.0
paths:
  /hello-world:
    post:
      tags:
        - Example
      parameters:
        - name: Protocol-Version
          in: header
          required: true
          schema:
            $ref: '#/components/schemas/protocol-version'
components:
  schemas:
    protocol-version:
      type: number
      const: 1

The following error occurs:

Uncaught (in promise) TypeError: o.allowedValues.split is not a function
    at de.inputParametersTemplate (api-request.js:520:1)

Since const can accept any data type, it is necessary to handle non-string types appropriately.
Specifically, when assigning schema.const to allowedValues, it should be processed in advance using getPrintableVal():

RapiDoc/src/utils/schema-utils.js

Lines 79 to 84 in 7f53d25

	// Set Allowed Values
	info.allowedValues = schema.const
	? schema.const
	: Array.isArray(schema.enum)
	? schema.enum.map((v) => (getPrintableVal(v))).join('┃')
	: '';

RapiDoc/src/utils/schema-utils.js

Lines 92 to 95 in 7f53d25

	info.allowedValues = schema.items.const
	? schema.const
	: Array.isArray(schema.items?.enum)
	? schema.items.enum.map((v) => (getPrintableVal(v))).join('┃')
