Invalid Date Error

Example error message

Cause

This error occurs when an invalid date is entered in a date input field. Common causes include:

  • Typos in the date format (e.g., 31/12/0220, 31/88/2020, 50/12/2020).
  • Strings instead of dates (e.g., "Test").
  • Incorrect numerical values (e.g., -1000).
Invalid dates prevent PDF exports from being generated.


When does invalid date error happen?

This error does not occur when manually entering a date, as the system automatically corrects typos and ignores invalid inputs. However, it can appear in:

  • Excel uploads – When a spreadsheet contains incorrectly formatted date values.
  • Data syncs – When information is pulled from another system and incorrect date formats are transferred.

Solution

To resolve the issue:

  1. Locate the invalid date entry – Use CTRL+F (Windows) or CMD+F (Mac) to search for the word "Invalid" or manually scan for incorrect date formats.
  2. Correct the date – Overwrite it with a correctly formatted date (YYYY-MM-DD) or delete it if no valid replacement is available.
  3. Verify exports – The error should disappear, allowing exports to function normally.

Called .custom on an Undefined Value / Reconciliation Not Found Error

Cause

This error occurs when a template references data from another template that is missing in the environment.

Solution

If the missing template is unnecessary:

  • Delete the template causing the issue.

If the template is needed:

  • The missing template must be added to file.

Steps to find the missing template (for admin users only)

  1. Go to Templates (firm level) and open the Reconciliations section.
  2. Search for the missing template’s handle.
  3. Add the necessary workflow or reconciliation to the client file.
Adding missing templates to a file may incur additional costs. If you have questions, please contact your Customer Service Manager before proceeding.

Example

  • System is trying to fetch data from 2018_tax_module, which is missing. 
  • To resolve it, locate the 2018_tax_module handle and add the Tax Calculation template associated with the BE Corporate Tax workflow.
