### Additional Information

_No response_

Start with the validateDataModelBindingsAny entry point and reproduce the validation described in the issue using an array map containing string values such as coordinates and text. Trace why passing the string and array type combinations produces the reported error; done means the described validation no longer fails incorrectly, with the relevant behavior covered by an appropriate test if one exists.
