Hi @patgat96 ,
To things here - firstly the parameter for your date needs to be
Text(DataCardValue7.SelectedDate,"mm/dd/yyyy")
and then in your Flow, you need to put it back to a Date - example below I just tested and it worked fine.

Also a bit of optimising of your code to avoid leaving Variables "hanging around"
With(
{
wJSON:
With(
{
wJSONI:
JSON(
Image1.Image,
JSONFormat.IncludeBinaryData
)
},
Mid(
wJSONI,
Find(
",",
wJSONI
) + 1,
Len(wJSONI) -
Find(
",",
wJSONI
) - 1
)
)
},
Set(
varFileLink,
'EasyUpload'.Run(
Last(AttachmentControl.Attachments).Name,
wJSON,
Text(DataCardValue7.SelectedDate,"mm/dd/yyyy")
).sharepointfilelink
)
);
