Apps Script Custom Function- Internal Error

Question

I\'ve just started playing around with Apps Script. I opened a new spreadsheet, accessed the script editor, and wrote the following simple function:

functio         


        

Answer 1

There appears to be a recently-introduced bug in the handling of Google Apps Script custom functions.

This is apparently the subject of Issue 5222. (I say "apparently" because that issue report isn't really clear. But good enough.) Star it to get more attention on it, and to receive updates.

Answer 2

As per Google's documentation:

A custom function call must return within 30 seconds. If it does not, the cell will display an error: Internal error executing the custom function.

This was indeed my case and I after a wee bit of code optimization I reduced the occurrence of the error to 10% of the cases.
