502 Bad Gateway

[C-B-Elite]

Hello,
I meet a gateway problem when I trying to get the file through http_request directly.
If the http request stream has no call back, then the file can be accessed , but if it has call back, the Nginx bad gateway error will be triggered
The http_request and http_streaming_call_back can be used before, but the call back can not work these days.
Is this problem made by the ic replica version upgrade?

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.

I have solved the problem.
The reason why I can’t use the http_streaming_call_back is I add the ‘content length’ into the http header.
It works when I delete it from the http head field.
