400 - System Use Only
Tip
The system_use_only error code will be returned if one or more properties have been provided in an API call but those properties are reserved for system use only.
For example, this error code would be returned if you made an attempt to provide a reference property when creating an object for which Sorted is responsible for generating references.
Tip
In general, Sorted API payloads are designed in such a way to avoid the possibility of this situation occurring and you are therefore unlikely to receive this error code.
