CustomBodyRender - Filters show Object Object

We have used customrender to draw a column having an array of objects. In the respective filter select field, it shows as object object. Is there a way for this? Or a workaround? Thank you

Start by reproducing the issue with customRender on a column containing an array of objects, then trace how that column's values are converted for the filter select field. Confirm the expected display format for object values and verify that the filter no longer shows "Object Object".
