Thank you very much all, for your answers. In my case I found the issue. You can locate a grid that is correctly configured with filters here
In my case I had configured the defaultColDef as follows:
defaultColDef: {filter: True}
This is not valid in version 32.
Instead, you will need to explicitly set the filter according to the data type of each column
const columnDefs = [
{ field: "text", filter: "agSetColumnFilter" },
{ field: "number", filter: "agNumberColumnFilter" },
{ field: "date", filter: "agDateColumnFilter" },
{ field: "choices", filter: "agMultiColumnFilter" }, # Enterprise
{ field: "no filter", filter: false },
]
