What does QUIC_STATUS_INVALID_STATE mean when StreamSend failed?

[panpur]

Hello,

I'm doing performance testing for my app by sending 1Gb of data to 50+ peers concurrently using API StreamSend.
I noticed there's a time when StreamSend was failed & returning QUIC_STATUS_INVALID_STATE.
This status only happened once & not able to reproduce again, but I'm curious to know what was causing it.

What are possible scenarios that may result in QUIC_STATUS_INVALID_STATE during StreamSend?

Thanks

That error comes from here. In this code path, if the peer shutdown the connection or stream, you'd get QUIC_STATUS_ABORTED, but otherwise (i.e. you shutdown them) you get QUIC_STATUS_INVALID_STATE.
