GOAL
When making an API call from MuleSoft using HTTP Connector, the API returns "400 Bad Request".The detailed error message can be seen in HTTP Wire logs:

HTTP/1.1 400 Bad Request

{
"error":{
"code":"","message":"An error has occurred.","innererror":{
"message":"Write failed for table row of type 'CustCustomerV3Entity'. Infolog: Info: Cannot create a record in Customers (CustTable). Customer account: ...
}
}
}

How can I retrieve the error message from the HTTP error response?
