如果发生错误，我该如何设置Google脚本触发器以再次运行？

Question

I have a google sheet to keep stack of live stock prices and portfolio valuations. Also, I have some script which runs once a day to provide a permanent record of the valuation. However, sometimes the stock prices do not load immediately, so the permanent record contains errors. What is the best way of fixing this ? For example, can I set a trigger to repeat after 30 minutes if there are errors in certain cells ?
I did try a loop to repeat the process within the script if there was an error, but as the maximum time google script can run for is about 5 minutes, it is not effective.

Answer 1

One possible solution is to set up a control sheet with two variables:

• has the script run today? True/False
• does the sheet have errors? True/False (by using the isError() formula on the portfolio sheet)

Trigger One: trigger a script first thing in the morning to set the "Has the script run today" value to 'False'.

Trigger Two: trigger a second script (say) every hour to check if

• the main script run today? False >> Run main script || True >> check for errors
• does the sheet have errors? True >> Run main script || False >> end

You could run Trigger Two more or less frequently depending on how many iterations it takes to get rid of all the errors.

But do remember that there is a quota for the total trigger run time as well: 90 min per day for a consumer account .
