Just a brief happy update 
I found a solution from looking at the other two similar discussions:
- Can’t sync my experiment from Pavlovia to the Builder
- Project unable to sync. Won’t permit local path
What I ended up doing was to try and upload a simple test sequence onto Pavlovia and realize my path is not set correctly. So I went back to my folder to look for the hidden .git folders to delete them (on MacOS, I went to the folder and held down the Command, Shift and Period keys: cmd + shift + [.] the hidden folder will appear transparent until you held down the same keys again).
And I just make sure I am using and set to the latest PsychoPy version (not on the avoid list) and re-uploaded my local experiment as a new project on Pavlovia and now it works!
Thank you again for your response and time.
