Something rare is happening, the code running locally with no problems, and even run with no problems in the server when I call it using "go main.go", but after build and set the systemctl service it's throwing an error 500:

/home/user/go/pkg/mod/github.com/gin-gonic/gin@v1.7.7/gin.g (Engine).ServeHTTP: engine.handleHTTPRequest(c) /usr/local/go/src/net/http/server.go:2879 (0x6663da) serverHandler.ServeHTTP: handler.ServeHTTP(rw, req) /usr/local/go/src/net/http/server.go:1930 (0x661a87) (conn).serve: serverHandler{c.server}.ServeHTTP(w, w.req) /usr/local/go/src/runtime/asm amd64.s:1581 (0x465200) goexit: BYTE $0x90 // NOP [GIN] 2022/04/05 - 01:16:51 | 500 | 9.701693ms | IP |

I'm using gin to handle http requests, this is a simple GET request:

func getAllTips(c *gin.Context) {
result := findAllTips()
c.IndentedJSON(200, result) }

called from main.go like this:

r.GET("/tips/", getAllTips)
r.GET("/tips/random", getRandomTip)

Does anyone knows how I can resolve this problem? Thank you all
