Good day Xevi.
Is the web data connector something that was developed "in house". If so, any chance you can post the web data connector? If not, do you know what version of the SDK it is using? Tableau updated the SDK for WebData Connectors a few versions ago.
If it's from a vendor, have you checked with them to see if there is an updated version?
This might be a part of a bug we have uncovered. Could you please try running Desktop with the WDC_QtWebEnginePort feature flag turned on and see if this fixes your issue?
1. Open a Terminal window (Applications > Utilities > Terminal ).
2. Type in the command below and press Enter to launch Tableau with the feature flag settings:
open -a /Applications/Tableau.app --args -DOverride=WDC_QtWebEnginePort
The issue is fixed when I run Tableau Desktop with the WDC_QtWebEnginePort feature flag turned on.
What does this exactly mean? How can we proceed so that all our customers benefit from this bugfix?
We are currently working on an in-product fix but a solution has not yet been found. The issue has occurred because of an upgrade in the browser used in Desktop from Qt Webkit 5.7 to Qt Webkit 5.10 and is only occurring on Macs. The WDC_QtWebEnginePort flag is a beta feature flag for a Qt WebEngine 5.10 upgrade that will likely occur in 2019.3. This is the only workaround as of now. Can you tell me, is this a custom WDC you are using internally or something you have built for external customers? Or is this a publically available WDC? How many people is this affecting? I'm going to add this thread to the bug and would like to have as many details as possible. I will also update you here when a fix is found.
Our custom WDC is something we have built for our customers, and is currently affecting many of them.
