503 error api gateway

Question

Newbie here: we are still in testing phase and hardly have any traffic on our api gateway but are getting 503 errors. Where can I start to try to fix this. It is random, we will get 200 responses, then 503.

Answer

Thats service unavailable.

A 503 error code is related to the backend integration and if the API Gateway API can't receive a response. This error might occur in the following scenarios: The backend server is overloaded beyond capacity and can't process new client requests. The backend server is under temporary maintenance.

Sounds like the endpoint may be maxed out or unhealthy/restarting?

Answer

I am having the same issue. Intermittent 503's mixed with 200's. This only started yesterday. I've been working on the project for 5 months and it's the first time I'm encountering the 503. I am the only user right now. It is occurring with every single endpoint in my App. Even the default "hello" endpoint, which takes nearly zero resources. Yes, the "hello" endpoint is giving my 503's about 30% of the time. And one again I'm the only one using it and I'm testing it once every 3 seconds. So there is NO WAY I am overloading it beyond its capacity.

OP, did you ever find a resolution?
