Exception Message = Invalid JSON Primitive error in Lacerte

SOLVEDby IntuitLacerte TaxUpdated July 14, 2022

When opening Lacerte to the clients list you receive "An error has occured in the Lacerte Tax Program." When selecting click here the error report shows: Exception Message = Invalid JSON primitive. This issue is caused by corruption within a piece of information the program utilizes for Intuit Link.

Before you start:

  • This article references default installation paths and uses YY to reference the tax year in 20YY format. C: will always indicate the local drive and X: will always indicate the network drive.

To resolve the error:

  1. Close Lacerte.
  2. Browse to the (IDATA) folder in Windows.
    • The default path is C:\Lacerte\YYtax\IDATA
    • If you don't know where the IDATA folder is open Lacerte in the prior year and from the Settings menu select Options. Review the data path. Typically, these are in a similar location.
  3. Open the Link folder.
  4. Right-click on the LinkClientsProgress.json file and choose Rename.
  5. Change the name to LinkClientsProgress.jsonold
    • If you get the message "If you change a file name extension, the file might become unusable. Are you sure you want to change it?" select Yes.
  6. Open Lacerte.
