1 year ago Hello @labulatif, I'm sorry to hear this problem. Is it possible that the double and/or int columns do contain only missing values? If not can you please have a look into the KNIME log file (in KNIME AP go to View->Open KNIME log) if you can find further information e.g. another stacktrace. Thanks for your help Tobias
Hi!
I’m trying to convert two columns Latitude and Longitude to geometry using the new node Lat/Lon to Geometry, however, the node is not executed and the following message is shown: Execute failed: construct from string not available yet
The issue seems to be related to the existence of string data columns with the Lat Lon columns. I tried to remove string data columns and the Lat/Lo to Geometry worked correctly.
I’m working with string, integer and double data type columns. My first try was to keep only latitude and longitude columns and it worked. After I tried to add string columns and it worked as well. After that, I added the integer columns and the node failed again. Then I removed string and integer columns, keeping only double columns (including lat and lon) and the node failed again, showing the following message: Execute failed: java.lang.IllegalStateException: Customization of entry point failed. With that message I’ve found at Knime Console the following message: WARN DefaultPythonGateway Python standard output: WARN DefaultPythonGateway Python standard error: Traceback (most recent call last):

Any idea on how to solve this?
