Describe the bug

Thank you for your work on this tool.

I am working on converting an openapi specification. However, I get an error saying that FileNotFoundError: [Errno 2] No such file or directory: '/Users/cloftus/Documents/schemas/common-core/link.yaml'. I am confused what this means since there is no reference to that file in my command or openapi file.

I am unsure if it might be related to this: #1579

To Reproduce

I am using the openapi json file at https://sta-edr.internetofwater.dev/openapi?f=json . All data is all contained in that file, but has remote references to other schemas defined via a community standard (i.e. "$ref":"https://schemas.opengis.net/ogcapi/features/part1/1.0/openapi/ogcapi-features-1.yaml#/components/responses/LandingPage"

Commandline reproduction:

pipx install datamodel-code-generator[http]
datamodel-codegen  --input openapi --output model.py

Expected behavior

I expected a model.py to be generated from my locally downloaded openapi json specification

Version:

• OS: MacOS Sonoma 14.3
• Python version: python 3.12 with pipx 1.7.1
• datamodel-code-generator version:

cloftus@host ~> datamodel-codegen --version
0.25.9

Additional context

My openapi specification file is coming from a valid server endpoint. It has lots of $ref values in it. I don't see anything that should be causing an issue however.

Full shell output: (tried as well with manually specifying the input type as --input openapi
