JS Simulation Configurator throws error on knime server

[tasjabfr]

Error message: nullpointer exception: null

Please find attached the workflow and files.

If we unwarp the JS Simulation configurator there is no error on knime server.

This workflow contains already a drop folder, where to use the one you have attached here? Another thing: Is there more information about the error on the server, because I don't have access to the server from here, maybe the log file from the server.

Hi Ahmad. The drop.zip folder contains all the files you need to upload in the first and second node of the workflow (first and second user input). We just sent them to make sure that you can execute the workflow locally in exactly the same way we do on the server. Unfortunately, we do not get a detailed error message on the server. The only message we get is the nullpointer exception: null. HTH, Tasja

I created a simpler version of the WF with the nodes:

1. String input: Sheet name
2. FSK Creator
3. FSK Editor JS
4. Simulation Configurator: NPE in webportal
5. Runner: Picks simulation entered in simulator

In the original WF the creator has the comment:

cant use the new xls file!

In this workflow I can. The spreadsheet is named testDose Response NoV QRA Model Annotation Excel templateV1.03 .xlsx and I had to change the sheet name to Generic Metadata Schema. Maybe that was the error in the original WF? tasjaWF.zip

@tasjabfr I got the following error when running your model in RStudio.

source('parameter_script_DR_ResultsFile_nvec10_nloop1.R') source('model_script_DR_ResultsFile_nvec10_nloop1.R') 4 1 Error in gzfile(file) : invalid 'description' argument

HI Miguel. Thank you for looking into this. I am a little confused because we all agreed that we would use the template V1.03. Octavio is alos using it in all of his workflows.... I am not sure what is wrong with the Excel sheet I used? It is unclear to me what causes this error.

Concerning the error in R we got the same yesterday and we fixed it. I am testing everything now with teh enw update and will come back to you if I run into problems....

Hi Tasja. The creator is using the 1.03 as agreed. I checked it in your WF and it worked for me. All I changed was the flow variable sheet containing the name of the sheet. The old spreadsheets have a Generic Metadata sheet IIRC while the new spreadsheet from Octavio has the sheet Generic Metadata Schema.

You can check in the WF I attached before https://github.com/SiLeBAT/FSK-Lab/files/2054642/tasjaWF.zip.

It seems weird to me because we had a string input defining Generic Metadata Schema, so I am not sure what went wrong....

Hi Tasja. I downloaded again the WF and files in drop and got again the same error. Did you change the file? If not, could you please sent me the fixed model? Thanks
