Failed to update artifact Error from server Status code 400 Details each value in cef_types must be a list of strings indicating the possible types

The error message suggests that there is an issue with the "cef_types" value in the artifact you are trying to update. The "cef_types" field should contain a list of strings indicating the possible types.

To fix this error, make sure that the "cef_types" value is formatted correctly. It should be a list of strings, where each string represents a possible type for the artifact.

For example, if the artifact can have two possible types "type1" and "type2", the "cef_types" value should be ["type1", "type2"].

Double-check the format of the "cef_types" value in your code or configuration file, and ensure that it is a list of strings indicating the possible types for the artifact
