+            This issue was not reproducible. Please check that your example runs locally and the following:
+
+             - Ensure the script does not rely on dependencies outside of `puppeteer` and `puppeteer-core`.
+             - Ensure the error string is just the error message.
+               - Bad:

+                 Error: something went wrong

+                 ```
+
+               - Good: `Error: something went wrong`.
+             - Ensure your configuration file (if applicable) is valid.
+             - If the issue is flaky (does not reproduce all the time), make sure 'Flaky' is checked.
+             - If the issue is not expected to error, make sure to write 'no error'.
+
+            Once the above checks are satisfied, please edit your issue with the changes and we will 
+            try to reproduce the bug again.
