How can control the paste of a string with AppleScript?

Question

In BBEdit and AppleScript I can loop through a string and set the string to the clipboard with:

set the clipboard to jsonString

I can then make a new text document and save it with:

set jsonParseFile to (name of project window 1) as text
save text document jsonParseFile to file ("some:location") without saving as stationery
set jsonParseFile to (name of active document of project window 1) as string

but when I try to paste the contents of the string with paste I get an error indicating that paste is not understood:

BBEdit got an error: active document doesn’t understand the “paste” message.

So when I remove:

set jsonParseFile to (name of active document of project window 1) as string

and use:

paste of active document

I get the same error but when I just use paste I'm returned the error of:

BBEdit got an error: Can't continue paste.

How can I paste the string into the file variable jsonParseFile which is the front most file without calling on:

tell active document of project window 1 to paste

but rather with something like:

tell active document of file jsonParseFile to paste

that passes jsonParseFile? When I search I haven't found anything beyond keystroke and I'm not wanting to use and when I check the dictionary for answers I'm not getting much:

This is a simple example how to paste a string into the active document

set the clipboard to "Hello World"

tell application "BBEdit"
    tell active document of project window 1
        paste
    end tell
end tell
