- Data preview freezes in presence of binary object as a string representation. The presence of just the binary object is totally fine, though. As follows the screenshot displaying the instability issue.
Just to confirm here as well as in Columnar Backend: Data Preview takes much more time to display or never finishes - #6 by carstenhaubold : the fix by @wiswedel to restrict the string length for rendering does mitigate this problem. You can try it out in the current KNIME nightly build.
