The problem described below is fixed! I was responding to the ping with a capital 'T' in "type". The code has been corrected.
I want to set up a new Discord bot to interact via an HTTP endpoint, but I can't get it to work. (aws lambda in golang, exposed through the aws api gateway)
Here's the main function :
func handler(request events.APIGatewayProxyRequest) (events.APIGatewayProxyResponse, error) {
rawBody := request.Body
fmt.Println("start")
// validate nacl header
err := validator.verifyRequest(
request.Headers["x-signature-ed25519"],
request.Headers["x-signature-timestamp"],
request.Body,
)
if err != nil {
fmt.Println("StatusUnauthorized")
return formatUnauthorizedResponse()
}
discordRequest := DiscordRequestDto{}
err = json.Unmarshal([]byte(rawBody), &discordRequest)
// validate ping
fmt.Println("test ping")
if validator.IsPing(discordRequest.Type) {
fmt.Println("is ping !")
return formatPingResponse()
}
return formatResponse("ok")
}In summary, it tests the validity of the header, then checks if it's a PING.
When I set up the Discord bot to use this api (in "INTERACTIONS ENDPOINT URL"), it tells me that the endpoint couldn't be verified. The log indicates an authorization error on the second request.
Yet the log shows me responding correctly to the PING on the first request (so the header validation passed).
However, I use exactly the same code on another project that works perfectly, so it can't be much!

Do you have any idea what I'm forgetting ?
