DashAI/front/src/components/datasets/DatasetModal.jsx:182

• Data type inference loses column renames: The handleInferDataTypes function (line 182) replaces the entire columnsSpec state with the inferred types. This will lose any column renames that were made before inference. After a user renames columns and then runs type inference, the renamed columns will revert to their original names. The updatedTypes should preserve renamed column names by mapping them correctly.

  const handleInferDataTypes = async (methods) => {
    setLoading(true);
    const formData = new FormData();
    formData.append("file", newDataset.file);
    formData.append(
      "params",
      JSON.stringify({
        ...newDataset.params,
        methods,
      }),
    );

    try {
      const response = await inferDataTypes(formData);
      const updatedTypes = Object.fromEntries(
        Object.entries(response).map(([key, value]) => [
          key,
          {
            type: value.type,
            dtype: value.dtype,
          },
        ]),
      );

      setColumnsSpec(updatedTypes);
