Error while importing a workflow

[besherh]

Hey folks,
I am trying to import a workflow (I have export it then trying to import), however it’s not working.
This is the error message:

I have also attached the logfile!
text.log (789.4 KB)

Anyone could advise?

Hi @besherh ,
Could you please review this documentation and then try to import the workflow again?
https://docs.knime.com/2020-07/analytics_platform_workbench_guide/index.html#workspaces

If the issue persists, please share the workflow that reproduces the error with us.

Thanks,
Sanket

What happens if you copy the .knwf file, change the extension to .zip, and open it with an unzip tool? Does it properly unzip or do you receive an error message? (the latter would mean that the file is corrupted, and the data probably lost entirely or partly).

[besherh]

It happens with any workflow I download from the hub, here is an example!

@qqilihq

properly unzip or do you receive

Yes, it’s uncompressed without any issues!

@besherh

Yes, it’s uncompressed without any issues!

cab you try and import it from a folder. If this does not work have you tried to re-install your KNIME version. Before that restart the installation with the option -clean in the knime.ini once.

Also could you provide us with more information about your installation and also a new LOG file in DEBUG mode.

@mlauber71

and

What will happen to my workspace and workflows in this case? It will all be removed?
What if the problem persists? Then I will lose all of my work, right?

@besherh your program and your work should be in separate folders. You can always re-install KNIME and keep your work:

Save Knime Workflow

you have three ‘locations’ concerning KNIME the place where the program files live (you can re-install that at any time) the place where all the workflows are stored the “knime-workspace” that should be somewhere else and should be backuped the temp folder where KNIME stores intermediate and unsaved data (that can be disposed once the knime-workspace is saved) This is the folder that contains your workflows: [image] This is how it looks within KNIME: [image]

Then: you should always backup your work and have versions ready. Since disaster can strike anytime regardless of your installation

Restore Knime workflows

@evert.homan_scilifelab.se I can offer up these threads. Unfortunately if the workflows would not integrate themselves into KNIME like this you might have to revert to a backup. Can you tell us more about your system and the circumstance where the data is being stored (is it some sort of cloud drive?).

Backup and Cloud Sync:

Workspace synchronizing in the cloud

@christianlondon you may want to take a look at these two threads: A simple backup system might look like this:
