[httpx.ReadTimeout: The read operation timed out] on schema introspection

[Anton-Shutik]

Times out when trying to get schema via introspection. Seems like httpx has default timeout of 5 seconds, it is not enough to load schema in the case.

Python 3.9.13
ariadne-codegen==0.14.0
isort==5.13.2
black==24.8.0

[tool.ariadne-codegen]
remote_schema_url = "https://host/graphql.json"
remote_schema_headers = {"Token" = ""}

The above exception was the direct cause of the following exception:

httpx.ReadTimeout: The read operation timed out

I was able to fix it by manually adding timeout=30 to the post call here

When working with remote schemas a higher default timeout value would be good, and also a --http-timeout parameter for the CLI.
