[MEGATHREAD] Script no longer running/triggering

[derekantrican]

This issue serves as a megathread for the topic of the script no longer triggering (NOTE: this is not the same as "script authentication issues" or "script hitting errors and not fully syncing"). This will allow us to direct people to a single place to get help on this issue. This top comment will be updated with information as we know more about the issue. Please add a comment about your setup* if you are seeing this issue and please add a comment if you have found workarounds.

The problem:

You may see some triggers that are disabled. This was an issue that existed with an older version of the script, but it may be possible that some users are still seeing it from time to time for whatever reason.

Note that although servers (like Google's and the service where your source calendar is) have redundancy and great uptime, they do have temporary issues from time to time. If you are receiving emails with a subject like "Summary of failures for Google Apps Script" and there is only 1 or 2 entries - this is likely normal & expected behavior.

Existing issues:

• install() function not self-retriggering properly #137
• New Calendar gets added but does still does not sync #161
• "Trigger disabled for an unknown reason" with V8 runtime #104
• Triggers disabled #79
• Triggers Randomly Fail #77

Suggested workarounds:

• Make sure you are using the latest code (⚠️ the version at the "Copy the script from here" link on the README may not be the latest!). Make note of your calendars (var sourceCalendars =) and settings, then follow these steps to make sure you have the latest code: https://github.com/derekantrican/GAS-ICS-Sync/wiki/Setting-up-the-script-manually . Then put your settings back.

*Sharing your setup:

As usual, if you are seeing this issue and none of the suggested workarounds help, please leave a comment here with the following:

• Screenshots (for this issue, open your copy of the script, go to the address bar, and change /edit to /executions and send us a screenshot)
• We'll probably want to ask you about your code and if you've made any modifications

Please do not leave any sort of "Thanks", "Me too", or "That worked" comment - I will delete them. Only comments that add to the conversation (details about your issue, suggestions, workarounds, etc) will be allowed.
