Possible Bug? Content-Type header in API

[CXƆ]

I would like to report a possible bug that I encountered while developing a Python client for the API. This client is intended to test if the connection can be established. I solve this with a GET request to /api/v1/ - without performing any further action. I use HMAC as the authentication method.

EspoCRM Version: 8.2.4

Steps to Reproduce:

• Send a GET request to https://example.com/api/v1/
• Check the response headers and the response body

Expected Behavior:
If the Content-Type header is 'application/json', the response body should contain valid JSON.

Actual Behavior:
The Content-Type header is 'application/json', but the response body contains the string 'EspoCRM REST API', which is not valid JSON.

Error Log: Python error when trying to parse the response as JSON:

if response.headers.get('Content-Type', '').startswith('application/json'):
      return response.json()
Error: Expecting value: line 1 column 1 (char 0)

Response-Header:

{
    'Server': 'openresty',
    'Date': 'Mon, 24 Jun 2024 21:53:34 GMT',
    'Content-Type': 'application/json',
    'Content-Length': '16',
    'Connection': 'keep-alive',
    'X-App-Timestamp': '1719243103',
    'Expires': '0',
    'Last-Modified':
    'Mon, 24 Jun 2024 21:53:34 GMT',
    'Cache-Control': 'no-store, no-cache, must-revalidate, post-check=0, pre-check=0',
    'Pragma': 'no-cache',
    'Strict-Transport-Security': 'max-age=63072000; preload',
    'X-Served-By': 'beispiel.de'
}​

Response Body:

 b'EspoCRM REST API'

Additional Information:

This error prevents the implementation of simple logic to process JSON responses based on the Content-Type header.

Note that you can use GET api/v1/App/user request to check connection.
