Hello,
We are currently using envoy gateway for some of our small services and want to expand envoy gateway to high throughput, low latency GRPC services. We tested GCP traffic director in the past with proxyless but we want to explore options to leverage envoy gateway in order to only have one tool to support and have multi cloud support (+ OSS is always a plus to review code and bugs).
I've been playing over the weekend with simple golang GRPC client/server setup with an envoy-gateway GRPCRoute setup but got kinda stuck on getting and parsing ADS response from the XDS server.
I get to the point of sending the follow ADS request:
2024/07/07 01:42:00 could not greet2: rpc error: code = Unavailable desc = network filters {[]} had invalid server side HTTP Filters {[name:"envoy.filters.http.grpc_web" typed_config:{type_url:"type.googleapis.com/envoy.extensions.filters.http.grpc_web.v3.GrpcWeb"} name:"envoy.filters.http.grpc_stats" typed_config:{type_url:"type.googleapis.com/envoy.extensions.filters.http.grpc_stats.v3.FilterConfig" value:"\x08\x01\x1a\x02\x08\x01"} name:"envoy.filters.http.router" typed_config:{[type.googleapis.com/envoy.extensions.filters.http.router.v3.Router]:{suppress_envoy_headers:true}}]}: no filter implementation found for "type.googleapis.com/envoy.extensions.filters.http.grpc_web.v3.GrpcWeb"
I'm fairly new to XDS and envoy-gateway so trying to see if anyone tried to acheive this setup before and some leads on where to go. I there any other request/endpoint I could query to get the GRPC endpoints behind the GRPCRoute in order to enable proxyless with envoy-gateway ?
I'm simply trying to get a POC to review that it could in theory works and perhaps build some extension in future ?

Which kinda works but I get the following error:
I've read the https://github.com/grpc/proposal/blob/master/A39-xds-http-filters.md doc but i'm not really sure if there is a a workaround, it seems like there is no option to completely ignore non optionnal with no implementation filters.
