Issue: When attempting to import or export a document using the TrueCommerce vSync Module within Dynamics Great Plains Enterprise (Dynamics GPE), you encounter the following error: 'Unhandled script exception: String overflow on set '{FieldName}' EXCEPTION_CLASS_SCRIPT_STRING_OVERFLOW'

Reason: The Dexterity Script Debugger is a resource-intensive debugging tool within Dynamics GPE that can prevent various processes from being able to properly write to or read from the SQL Database, as the debugger attempts to utilize the same processes and resources as the integration.

If it is determined that the Dexterity Script Debugger was left active, disabling it and restarting Dynamics GPE should resolve the issue. The Dexterity Script Debugger is enabled by modifying the Dex.ini file — specifically by adding ScriptDebugger=TRUE to the [General] section. To disable it, the setting must be reverted

Navigate: C:\Program Files (x86)\Microsoft Dynamics\GP[version]\Data

Open: Dex.ini

Set: ScriptDebugger=FALSE

Save

Restart Dynamics
