This error occurs when the ast.literal_eval() function encounters an Ellipsis object in the input string or node. The literal_eval() function is used to safely evaluate strings containing Python literals, such as lists, dictionaries, tuples, etc.

In this specific case, it seems that the input string or node contains an Ellipsis object, which is not a valid Python literal and cannot be evaluated by literal_eval().

To fix this error, you need to ensure that the input string or node does not contain any Ellipsis objects. You can do this by checking the input data and removing any occurrences of Ellipsis before passing it to literal_eval()
