Issue Summary

I'm trying to create a custom dashboard template. The charts on my dashboard use a single Google Sheet as the data source, but I am unable to create a template from the dashboard. 

Steps to Reproduce

1. Create a dashboard that has charts created using a single Google Sheet as the data source. 
2. Select 'Publish as template' from the dashboard sidebar. 
3. Name the template and create a description. 
4. Click 'Publish'.

Expected Results

The dashboard would be added as a custom template within the Atlassian Analytics instance. 

Actual Results

The error message in the screenshot below appears in the bottom left corner.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available.
