Unable to use https proxy for a https URL

[rghv404]

I'm using scrapingbee proxy as :

proxies = {
    'http://': f'http://{SCRAPINGBEE_API_KEY}@proxy.scrapingbee.com:8886',
    'https://': f'https://{SCRAPINGBEE_API_KEY}@proxy.scrapingbee.com:8887'}

However I get below error:
RuntimeError: Attempted to add a TLS layer on top of the existing TLS stream, which is not supported by httpcore package

As far as I understand, https proxies were enabled in httpcore package here: encode/httpcore#722.
What could be causing this?

P.S Using requests library with the above proxy works just fine:

res = requests.get(
    url=MY_URL,
    proxies=proxies,
)
