Get list of devices

Hello everyone. Maybe someone will help me here. I am faced with the following problem. There is a lora-app/net servers, as well as a lorawan backend, it’s all hosted on gcp kubernetes. Recently I ran into a problem that in lora-application server I can’t get a list of devices or create a new device, I get error 502 (crashes by timeout), but all other operations are performed successfully (for example, the list of gateways, or the rest of the functions work well). Probably, anyone also have the same problem?
