Unable to load workflow due to missing extensions

KNIME Server
1

Hi,
I uploaded a workflow onto the server and get an error when executing:

Could not load workflow ‘http://172.31.95.46:8080/knime/rest/v4/repository/Prescription%20Algorithm%20v0.105:data’: Errors loading workflow ‘Prescription Algorithm v0.105’ due to missing extensions:

Extension: KNIME Base nodes
Nodes: Table Column to Variable, Table Column to Variable, Table Row to Variable, Table Row to Variable

Extension: KNIME Excel Support
Nodes: Excel Reader, Excel Reader, Excel Reader, Excel Reader, Excel Reader

I am using the KNIME Server on AWS (from the Marketplace), and am using the current KNIME AP 4.3.1.

Thanks,
Harold

Hello @haroldyin,

Hi @ipazin,

I am assisting with the issue above.

Can you please describe the upgrade process for upgrading the BYOL version of the AWS Marketplace?

Is it possible to do the disk-swap upgrade without requiring a new license (since license is linked to instance-id)?

Kind regards,
Phil.

Hello @philipwigg,

KNIME Server update process on AWS is same as regular server update for on premises KNIME Server so I suggest you follow bottom guide to update from 4.11 to 4.12 version. This way you don’t need new license.

https://docs.knime.com/2020-12/server_update_guide/index.html#update

If you swap the workflow repository volume from one instance to another then you would need a new license.

Hope this helps and you’ll manage to do successful update :wink:

Br,
Ivan
