Question

I’m trying to move my big mails from Gmail to a Google Site with a Google Apps Script. The script runs without problem but when the attachment size exeeds 10Mo an error occured :

“Server error, please try again later…”

var att = ms[m].getAttachments();
for (var a=0; a<att.length; a++){
tab[3][m][5][a] = att[a].copyBlob();
    ...
}
...
var atttach = post.addHostedAttachment(tab[3][i][5][b]);
...

Answer 1

It seems that their is a blob size limit in Apps Script as 10 MB. Probably that is causing the error.
Check the discussion in Issue Tracker where Evin Levey says

We some some strict internal limits that we’re working on raising…
It should now be at 5MB, with 10MB coming shortly.
