502 Bad Gateway

I don’t know much about this but it looks like your StreamingToken type may be missing one or two fields.

dfinity/agent-rs/blob/076051a601dc5080ad6baf6d6034a109cca3ab00/ic-utils/src/interfaces/http_request.rs#L23-L30

Custom StreamingCallbackToken

I think you have to abide by this interface (since it’s what the Rust icx-proxy that’s running on the boundary node will expect and parse). So you can name the function anything you want (doesn’t have to be http_request_streaming_callback) but you can’t change the token parameter I don’t think. The code where the icx-proxy actually calls your asset canister is here.
