Many thanks for the rapid response, Martin. That worked perfectly!

May I ask your advice on another little problem, please? I have created archives for three Twitter accounts, each set to sync daily using your app. The archives are here:

https://k0711.github.io/keithfrankish-twitter/
https://k0711.github.io/philhellenes-twitter/
https://k0711.github.io/mariakasmirli-twitter/

They seem to be working OK. (There’s the same dating problem with the last one, but I know how to fix that now.) The problem is that roughly every other day I get an auto error message from Google Scripts. Here’s a sample:

************
Your script, Twitter Archive Update to Github, has recently failed to finish successfully. A summary of the failure(s) is shown below. To configure the triggers for this script, or change your setting for receiving future failure notifications, click here.

Can you help me diagnose the problem, please? I’m not even sure which of the three accounts is causing it. The error doesn’t seem to be generated on every sync.
Best, Keith
