API is generating a 502 (seemingly intermittently)

I am using GAS to read a table into an array (150 rows and 50 columns) and after seemingly working it now seems to to have stopped working, generating this error:

Exception: Request failed for https://coda.io returned code 502. Truncated server response:

502 Bad Gateway

502 Bad Gateway

(use muteHttpExceptions option to examine full response) getRow @ Coda.gs:548

I am at the limits of my technical knowledge so a bit of direction would be much appreciated.

Hi Clifford! Sorry for the trouble. Mind contacting support via the in-product support (click the question mark in the bottom right when using Coda) and providing a link to your doc and the relevant snippet of GAS code and we can look into this further?

Hi Jonathan, I did this last night (UK time). Thanks.
