Delphi Request.ContentFields.Values['something'] is not showing values on MIME data - delphi

Question

In TWebModule1.WebModule1WebActionItem1Action(), using Request.ContentFields.Values['content'] or any name, I cannot get any values from the POST, but if I use Request.ContentFields.DelimitedText, I will get the values. Where did I go wrong?
This is the values DelimitedText returned:
