Can't install extension "Indigo KNIME integration"

[ilia_nikitin]

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
