When creating a new task with a SAP Business One Connector step, as soon as you try to choose the SAP Business One object an error occurs which displays
Unable to contact web service
As a result of this no objects or fields appear for mapping.
Issue occurs after upgrade from 3.0.1 to 4.0.1 when schemas are not refreshed in the global configuration. The error will appear at step configuration when selecting an object.
Ensure all schemas are refreshed after upgrade of the tools.
