Hello!
First, I tried the “drag and drop” method to install the “Indigo KNIME integration” extension, however I received the following error:
“Could not query updates site for missing extensions
HTTP Server ‘Internal Error’: https://hub.knime.com/epam-lsop/extensions/com.epam.indigo.knime.feature/latest/content.xml
HttpComponents connection error response code 500.”
Then I tried another way. I added link with extension to File > Preferences > Install/Update > Available Software Sites. But further attempt to install via File > Install KNIME Extensions... also failed.
Hello @ilia_nikitin,
Welcome to the Forum.
It looks like an issue with the update site. Could you please check the Available Software Sites in your KNIME AP?
- In Modern UI : Go to Preferences → Install/Update → Available Software Sites.
- Make sure that the correct update site is listed.The URLs below
(https://hub.knime.com/epam-lsop/extensions/com.epam.indigo.knime.feature/latest/content.xml and https://hub.knime.com/epam-lsop/extensions/com.epam.indigo.knime.feature/latest) are not valid update sites.
A valid update site for community extensions typically looks like this:
https://update.knime.com/community-contributions/trusted/5.4
(Replace 5.4 with your KNIME AP version if it’s different.)
It should look something like the below:
You can find more information on the update site here.
Hope this helps.
Best,
Keerthan
