Container go down after some curl request

[Monirzadeh]

After send request with curl every 15 second, I get this error and server get down after that

thread 'actix-rt|system:0|arbiter:0' panicked at 'called `Result::unwrap()` on an `Err` value: Utf8Error { valid_up_to: 2697, error_len: None }', src/endpoints/create.rs:93:69

I should restart container, any idea to solve the problem?
