Bug in Geoprocessing.ExecuteToolAsync("Append") when using field mapping / Shapefile

Question

Problem

Mapped Field does not get filled with content from source Shapefile

Situation

I do have a shapefile containing the following columns

FIDShapeOID_Title

This Shapefile needs to be converted into an existing FeatureClass (with different columns) located inside the fgdb named "ExistingFeatureClass" containing the following columns

OBJECTIDShapeOID_Name

So the main goal is to convert and fill the "Name" field with its content from "Title" located in the Shapefile.

The below code ALWAYS result into "<Null>" for the "Name" column

var Environments = Geoprocessing.MakeEnvironmentArray(overwriteoutput: true);
var ToolPath = "Append";
var ShapefilePath = "D:\PathToShapefile\shapefile.shp";
var FieldMappings = "OID_ "OID_" true true false 4 Long 0 0,First,#,D:\PathToShapefile\shapefile.shp,OID_,-1,-1;Name "Name" true true false 254 Text 0 0,First,#,D:\PathToShapefile\shapefile.shp,Title,0,254";

var Parameters = Geoprocessing.MakeValueArray(ShapeFilePath, "ExistingFeatureClass", "NO_TEST", FieldMappings);
await Geoprocessing.ExecuteToolAsync(ToolPath, Parameters, Environments);

While running the code with indentical Parameters using the Dialog (see below) all fields are correctly mapped and only a "Run" is pending for the success

Result = await Geoprocessing.OpenToolDialogAsync(ToolPath, Parameters, Environments);

Any ideas on how to resolve this? Is this a BUG?

Could you please share your data? We'd like to try with your data.

Could you please share your data (at least schema)? Or, you can try Wolf's way:

"AREA ""AREA"" true false false 8 Double 0 0,First,#,{shapefilePath},AREA,-1,-1"

Create a variable named shapefilePath and the path of your data to it. Then try and let us know. You can email me at nahmed@esri.com

When I played around with my sample to find the difference I was not able to get the 'mapped' field populated anymore.  I passed the sample on to the GeoProcessing project engineer, i really can't see anything wrong with the code.  Also, I think the GP tool should report a warning or error if the 'mapped' field cannot be populated.  I will let you know if we find the cause of this issue.

Thanks for you patience and reporting this issue.
