File Upload Widget Error

Hello,

I have a workflow which uses a File Upload Widget to allow file selection in a components Data app view.

This worked in earlier versions of the workflow but seems to have broken. I’m not sure if this is a consequence of moving to a new version of KNIME.

Whenever I try to change the chosen file to anything other than the default file the Data App View shows “Input is required” in red, and when I move away it reverts to the default. If I try to execute with the new file I get the following error.

Error (root:157)
testValidityOfPage failed with error: Client-side validation failed. Please check the page for errors.

When I replace the default file, it executes as expected with the updated file address.

Any ideas on how to correct this?

I’ve provided the component at the below link. https://hub.knime.com/2197929m/spaces/Public/File%20Import%20Issue/File%20Import~hYHnoUqLzWdMdqFG/current-state
