Content decoding issue when connecting REST with http - apache-camel

Question

I am attempting to bridge a REST route to an upstream http service. There is an issue with decoding content - ERR_CONTENT_DECODING_FAILED when viewed from chrome. I assume this is gzip related. I am new to apache camel, so I am not sure where I went wrong.
Here's the route:
class RestRouteBuilder : RouteBuilder() {
override fun configure() {
restConfiguration().apply {
component = "undertow"
bindingMode = RestBindingMode.json
port = "8082"
scheme = "http"
}
rest("/airlines")
.get("/").produces("application/json").to("undertow:http://localhost:8080/airlines?bridgeEndpoint=true")
}
}
How would I return the content from the service on 8080 successfully?

Answer 1

I did some more reading and discovered that I was using bindingMode improperly. The 'Binding to POJOs' section of https://camel.apache.org/rest-dsl.html should explain everything for any newcomers with this same issue. In my particular case, the fix was simply to remove bindingMode from the rest configuration. This is safe in my example because I have no incoming message required to be unmarshalled - all GETs.
Working code:
class RestRouteBuilder : RouteBuilder() {
override fun configure() {
restConfiguration().apply {
component = "undertow"
port = "8082"
scheme = "http"
}
rest("/airlines")
.get("/").produces("application/json").to("undertow:http://localhost:8080/airlines?bridgeEndpoint=true")
}
}
