Problem retrieving annotations from sqlite3

Thanks Logan, that’s works now but with a little problem.
The first time that you tri to make a coment or a line (underline) the console show this error
PayloadTooLargeError: request entity too large

and don’t save nothing, the second time the comment is saved, if you wait a minut or change the tool for the annotations make the same, the first time this error and the second time save the annotation.

Any ideas??
