Environment
- OS: Windows [specify your version, e.g., Windows 10/11]
- WDC Version: 3.0
- Connector Type: [Custom/Tutorial connector - specify which]
Problem Description
My signed WDC 3.0 connector intermittently fails to launch the browser interface. Instead of opening the connector's web UI, Tableau only displays a generic "Server, Username, and Password" authentication dialog.
Steps to Reproduce
- Place the signed .taco file in My Tableau Repository\Connectors
- Open Tableau Desktop
- Click on the connector from the list
- Expected: Connector's browser interface opens
- Actual: Generic authentication popup appears instead
Hi @Anoop Singh
The issue you're encountering, where a signed WDC 3.0 connector intermittently fails to launch its browser interface and instead displays a generic authentication dialog, is a known problem. This behavior occurs because Tableau doesn't have a built-in UI for OAuth authentication, so it defaults to the standard authentication dialog. https://github.com/tableau/webdataconnector/blob/master/docs/wdc_oauth_tutorial.md
To resolve this, ensure that your connector's code properly handles the authentication phase. Specifically, during the authentication phase, your connector should display the necessary UI to prompt users for authentication information. This involves setting the `authType` to `tableau.authTypeEnum.custom` in your connector's initialization function. https://github.com/tableau/webdataconnector/blob/master/docs/wdc_authentication.md
Additionally, verify that your connector is correctly handling the `tableau.password` property to store sensitive information like access tokens. This property is designed to securely store such data and is not written to disk, ensuring that credentials are managed appropriately. https://github.com/tableau/webdataconnector/blob/master/docs/wdc_authentication.md
By implementing these practices, your connector should consistently launch its browser interface without defaulting to the generic authentication dialog.
