The unhandled exception error is returned after the workflow is run.

Cause

In Designer 2019.1.4, there is a known issue where adding multiple browses to a tool simultaneously causes Designer to crash when the workflow is run. This is because when the Browse tools are added, the configuration is not finalized for each tool. A fix is being developed. In the meantime, please see the following workarounds.

Solution

Upgrade to the latest release of Alteryx Designer (2019.1.6).

Workaround A

  1. Add all Browse tools one by one.

Workaround B

  1. After adding Browse tools, save the workflow before running it.

Workaround C

  1. Add All Browses with Right-click > Add All Browses OR Ctrl + Shift + B
  2. Apply the configuration to each Browse tool individually.
    1. Click each added Browse tool to open the Configuration window.
    2. Click Apply (the check-mark in the bottom left corner of the Configuration window)

    3. Repeat for each added Browse tool.
