Google Apps Script: What does "Deserialization of continuation failed" mean?
google-apps-script
Solution
When `Browser.inputBox` or other script pausing operations are used (eg. the debugger) and are waiting end user interaction, the script is "serialized" (fancy word for stored) as a continuation.
If you are able to narrow down this error in some reproducible scenario, please lot an item in the Issue Tracker. Or perhaps look through other reported with continuation - https://code.google.com/p/google-apps-script-issues/issues/list?can=1&q=continuation
Problem
I wrote a Google Apps Script to do some fancy computation in a Google Spreadsheet. The script reads values from two columns in the sheet, and writes its output to a third column. When the script is invoked, I call `var someVar = Browser.inputBox("prompt");` 3 times in order to get -- from the user -- the column names of the 2 input and 1 output columns. For example, if a user wants the script to read from columns A and B and write to column C, he/she should specify the letters 'A', 'B', and 'C', in the specified order, in the 3 input boxes that pop up. The script executed successfully a number of times. Lately, after the first `Browser.inputBox` call (meaning after filling some value in the input box, and pressing OK), a "Deserialization of continuation failed" error occurs (it is shown in a red, toast-like message box at the top of the page), and the script stops executing (meaning the 2 remaining input boxes do not appear). I googled for "Deserialization of continuation failed", I got literally 2 results. Both of them are useless. Does anyone know what is this error message supposed to mean, and how to fix it? Any help would be much appreciated.
