When I try to insert a record in a custom data table though POST request with JSON data, if I submit a wrong format, for example, leave a comma at end of the last field, I will get error

{
"$diagnoses": [
{
"$severity": "error",
"$message": "X3 engine error: Inconsistant data",
"$stackTrace": "X3 engine error: Inconsistant data\n<empty stack>"
}
]
}

Once this error happens, I get this error for any requests even a simple query for customers. Close all sessions don't help unless restart X3 services. But I cannot restart X3 services during day when users are all in. 

X3 Version 11, Update R080.002
