When using Strategy Workstation on Mac to import data through a local mode connection (not connected to any environment), authenticating to any one of the cloud-based connectors or Community Connectors and selecting tables to import results in the following error message.
Error importing following files. Please check the files or delete them. [Get data failed. Error in importing files. Please check the file to import. Error type: Data Import Error. No data was loaded. Node JS command may exit unexpectedly.]

This issue affects Strategy Workstation 2019 Update 7 running on Mac OS version 10.15.4 and later.
The following is a list of affect Cloud connectors:
List of affected Community Connectors:
This defect is due to the incompatibility of MacOS 10.15.4 (and newer) and Nodejs 10.15.3, which is a component that will spawn a process to run the node command to get data when importing data from any of the connectors listed above. Under such condition, the node process will be directly killed, hence the error. As Strategy Workstation 2019 (and all available updates) use NodeJS version 10.15.3, it will show this error message with any MacOS 10.15.4 (Catalina) on Mac.
Upgrade Strategy Workstation to version 2020 or later, which already includes NodeJS version 10.20.1. This version is compatible with MacOS 10.15.4 and later.
To work around this issue in Strategy Workstation 2019, you can do the following:
