@vitor Thanks that helped I ran into the exact same issue I had to create a workflow to disable encoding the {query} parameter option.
Previously I was able to get this working with Web search now it encodes the % itself breaking the Jira search.
The working config is here for anyone who is looking for a fix.
This Web search config as shown below no longer works 💔
We need to do this Create a workflow as mentioned here
Then uncheck encoding for {query} placeholder
Now disable the Web search and only have the Workflow enabled 👍
