string to Document error

KNIME Analytics Platform
1

Hi
Running Knime 5.3.1

I am trying to run a workflow using the String to Document node. The error is " Execute failed: Cannot invoke “java.net.URL.getPath()” because “fileUrl” is null"

I am using the table creator as the input so there are no paths as far as I am aware.

The log error is:

2024-08-23 15:29:12,182 : ERROR : KNIME-Worker-16-Strings to Document 3:2 : : Node : Strings to Document : 3:2 : Execute failed: Cannot invoke “java.net.URL.getPath()” because “fileUrl” is null

Any thoughts please ? Thanks

Hello @mgirdwood,

Could you try uninstalling and then reinstalling the KNIME Text Processing Extension? Alternatively, using a fresh installation of KNIME might help. Also, can you check if the following file is present in your KNIME installation?

yourInstallationFolder\plugins\org.knime.ext.textprocessing.models_5.3.1.v202301131100\opennlpmodels\tokenize\en-token.nbin

Please note that the version number of the plugin might be different.

Best,
Keerthan
