Frequently Asked Questions

Why is my micro returning a 502 Bad Gateway?

The response comes from our gateway, which is a reverse proxy between a client and your micro. If there is a runtime error when invoking a micro, the proxy responds with a 502 Bad Gateway.

In order to debug 502 responses, you can use deta visor which show you real-time logs of your application. Navigate to your micro's visor page from the UI or use the deta cli command deta visor open to view the error logs. If there are no errors in your logs, please contact us.
