SSIS Error (Union All + Data Conversion)

I received the following error message using Union All tool in SSIS after converting data type using data conversion.

TITLE: Microsoft Visual Studio — — — — — — — — — — — — — — — Error at LOAD Data Flow Task [Union All [695]]: The metadata for “Union All.Inputs[Union All Input 1].Columns[xxx]” does not match the metadata for the associated output column. Error at LOAD Data Flow Task [Union All [695]]: Failed to set property “OutputColumnLineageID” on “Union All.Inputs[Union All Input 1].Columns[xxx]”. — — — — — — — — — — — — — — — ADDITIONAL INFORMATION: Exception from HRESULT: 0xC0204006 (Microsoft.SqlServer.DTSPipelineWrap) — — — — — — — — — — — — — — — BUTTONS: OK — — — — — — — — — — — — — — — 

To fix this issue, please follow the below steps.

1. Check your data types, make sure that the Union All input data types are the same
2. Drag and open Union All
3. Delete the whole table (they automatically show every output columns and union columns)
4. Re-write the columns’ name and map the union columns
5. Click OK

This issue should be solved :)
