Undocumented HTTP error status when trying to pull data from Typeform API?

We are trying to pull both forms and responses data from the Typeform API.

However, after some time running, the API suddenly returns an HTTP error that does not seem documented [doc]

"Request to failed with status code 499 and error message None",


Did anyone have this issue before?  If so, can you provide some context on why this is happening?


Thank you!

@mathio do you happen to know anything about this error message? 


the support team answered me by email that this error means that the client unexpectedly closed the connection meanwhile the server is still processing the request.

I will have that in mind now and debug deeper with this new context.

Thank you!
