503 errors with an airtable + google slides app

Hi everyone!
I made a very simple app to generate slides with datas from an airtable database.
But anytime I run the app, I get Runtime errors (503). It happens not all the time, but enough to make the app impossible to use.
Also there are only three lignes in my airtable database.
Is there something to do on Google Slides administration?
Thank you for your kind responses.


Hi @Oliviers

​Error 503 is a temporary error from Airtable which occurs when their server is down. For more details, refer to the below link:


To prevent the scenario from getting affected by the above error, I recommend using one of the retry workarounds, which would be more straightforward. For most cases, including this, I’d recommend the one with the Break directive.

If you need assistance, don’t hesitate to contact me.
