Erro 500 no postman

Estou tentando usar o postman, porem esta dando esse problema:
timestamp": “2021-08-06T22:04:15.692+00:00”,

"status": 500,

"error": "Internal Server Error",

"path": "/users"

Alguém sabe como posso resolver?

Estou usando o Eclipse

Ocorreu alguma exception no servidor. Veja no console do eclipse para ver se imprimiu alguma stacktrace.

Sim, imprimiu isso:

O erro parece ter sido numa consulta feita ao mongodb:

com.mongodb.MongoQueryException: Query failed with error code 2 and error message 'Field 'locale' is invalid in: { locale: "user" }' on server localhost:27017

A consulta deu erro acusando o campo locale como inválido. Verifique se esse campo realmente existe e se vc está usando ele corretamente na consulta.
