Micronaut Declarative HttpClient Timeout

Question

I have this declarative client:

@Retryable(attempts = "5", multiplier = "1.2")
@Client("\${client-url}")
@Headers(
    Header(name = USER_AGENT, value = "Micronaut Http Client"),
)
interface MyApiClient {

    @Get("/locations?location={location}")
    suspend fun validationLocation(@QueryValue location: String) : LocationResponse
}

I've set the client timeout to 30s with:

micronaut:
 http:
    client:
      read-timeout: 30s

And randomly I am getting:

Client <package> received HTTP error response: Read Timeout

What can the cause be to this very annoying behaviour?

This question seems to concern the same issue: Micronaut ReadTimeoutException

Apparrently the configuration is not injected. You might have to set it programmatically.

Is there any documentation on how to set it programatically ? – Shrinath Mar 23 '22 at 14:57

Apparently removing the suspend from the function and making it return a Single<LocationResponse> made the time-outs disappear.
