Hi @Troy Tessalone
So I have found out what happens with Dropbox.
With the image file, we shall not get the file from the dropbox direct download URL. We will need to use the share URL and format the parameter from dl=0 to dl=1.
In this way, the image file will be the completed version. The direct download link is dynamic, the moment from the data out of Dropbox New Added file Step 1 is an initial version of the link of its represented file which is potentially not fully uploaded and with some grey area on it.
Difficult explaining it with words... But it seems to be fixed as long as we don't use the direct download link for the next step to get the file.
@blueli Ahh, thanks for coming back to share that solution with us! I’m sure others running into the same issue will benefit from knowing this.
