What could cause this error at checkout on SCA "SyntaxError: Unexpected token 'S', "Script Exe"... is not valid JSON"

AI generated answer (using internal Slack threads):

The error at checkout on SuiteCommerce Advanced (SCA) "SyntaxError: Unexpected token 'S', "Script Exe"... is not valid JSON" could be caused by a number of factors. Here are some potential causes based on the provided Slack threads: 1. AvaTax Bundle Issue: There seems to be a recurring issue with the AvaTax bundle, particularly with versions 6.2 and 6.3. This bundle could be causing the error at checkout. One user mentioned that the issue was related to the new functionality for GSTIN (India taxation) in the One World bundle. They suggested editing the AVA_Transaction_Client and removing the validate line function, which resolved the issue for them. However, this solution is only applicable if you're not using the India taxation feature. 2. Script Execution Context: If the error is occurring during a checkout process initiated from the webstore, ensure that the "Webstore" context is selected in the context filtering tab on your script deployment. If it's not selected, the script may not execute during the checkout process, leading to errors. 3. Exception in User Event Scripts or Workflows: An exception thrown in a user event script or workflow could prevent subsequent events from running, leading to errors. Check your user event scripts and workflows for potential issues. 4. Incorrect Script Deployment: An incorrectly deployed script could cause errors. For example, deploying an electronic bank payment script to Purchase Orders, which doesn't make sense, could lead to errors. Remember to thoroughly test any changes in a sandbox environment before deploying to production to avoid disrupting your live site. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
