Error Expression Eval Tag History

i have some issue when i try to binding my time series chart to my data on dropdown, i have this error massage and try to figure out but still not have idea

The expression mode of the tag history binding expects a very specific format.
IIRC, it should be a list of objects, each with a "path" property. I'm willing to bet you don't have the proper format.

See this for how to do it:
