Can you please send an email to appsupport@monday.com so we can take a closer look and give this some following?
Please include in the email the mutation you are using, the error message, item ID, board ID, account ID and if you can, a timestamp (when you received the error. Date, hour, minute and location).
To fix this, check with your API provider to see if there is a testing environment that doesn’t utilize caching. Alternatively, double check your API call on a different machine or with a different set of credentials. You can also check your API documentation to see if there’s some cache invalidation method available.
