Urllib error when trying to use list inside a form-data #1394
Description
Describe the bug
I have an API that accepts a JSON list inside form-data, so the request is expected to look like this:
input=[{...}, {...}]
However, when I pass the list to the generated client, the request fails with the following error.
Could you please take a look and let me know what might be going wrong here?
from openapi_client import ApiClient, Configuration, DefaultApi, SubmitPostRequestInput, SubmitItem
config = Configuration()
config.host = "https://api.example.com"
api_client = ApiClient(configuration=config)
api_instance = DefaultApi(api_client)
request_input = SubmitPostRequestInput(
[
SubmitItem(flag1=True, flag2=False),
SubmitItem(flag1=False, flag2=True)
]
)
api_instance.submit_post(input=request_input, inlcude_ses=True)With the generated client and the code above I am getting the following error
