Error when attempting to save threads and attachments to yyyy/MM folder structures

[ahsee]

I'm attempting to have both threads and attachments saved in the same folder, grouped by subject, nested within date-based sub-folders.

I attempted to follow the methodology employed in #36 however I'm getting unexpected results.

I am sure I am getting something wrong with the naming convention for the folder value in config.gs, but I've tried many combinations without success. Sometimes I can get the attachments saving with correctly labelled folders, but the threads get saved in erroneous folder names.

Example:

Payslip.msg (with attachment "PayslipJuly.pdf"),
Sent July 2022
With label 'finance-related-payslips'

Expected outputs (2 files in same path):
Payslips > 2022 > July > Payslip > Payslip.pdf (formerly .msg)
Payslips > 2022 > July > Payslip > PayslipJuly.pdf

Actual output
Payslips > YYYY > MM > Payslip.pdf (formerly .msg)
No attachments.

Artefacts:

Global filter (just to confirm I'm not leaving out anything relevant):

    // Global filter
    "globalFilter": "-in:trash -in:drafts -in:spam",

Offending rule:

// Processing rules:
"rules": [
  {
    // Store threads marked with label "Finance Related/Payslips" in the folder "Payslips" as PDF document.
    "filter": "label:finance-related-payslips",
    "saveThreadPDF": true,
    "folder": "Payslips'/yyyy/MM/%s",
  },

Appreciate any assistance as I am sure I am getting a lot wrong - I am sure this is a very powerful tool once I get the hang of it!

I encountered this error as well, I believe the processThreadToPdf() function does not create the folder name as expected so this occurs in any email that uses "saveThreadPDF": true.
