Adaptive Card Action.OpenUrl not working for certain URLs in Microsoft Teams bot

Question

I am working on a Microsoft Teams chat bot using Microsoft Bot Framework. The bot sends an Adaptive Card containing some text and the following Action:

{
    "type": "ActionSet",
    "actions": [
        {
            "type": "Action.OpenUrl",
            "title": "View in dashboard",
            "url": "${url}"
        }
    ]
},

The URL is of the following form (edited to remove identifying info):

https://internaldomain.net/dashboard/share/134590h9?overrides=[{"query":"//dataSources","key":"account","replacement":"accountName"},{"query":"//*[id='Cluster']","key":"value","replacement":"clusterId"},{"query":"//*[id='NodeId']","key":"value","replacement":"nodeId"},{"query":"//*[id='ContainerId']","key":"value","replacement":"containerId"}]&globalStartTime=1591552800000&globalEndTime=1592460000000&pinGlobalTimeRange=true

The URL is generated and passed into the url property using a JSON templating library, and I can print the URL in the console so I know it is set properly. Also, I can run the bot in the Emulator and open the link that way. However, when I run the bot in Teams and try to open the same exact link by clicking the action button, nothing happens. If I change what URL is passed in, e.g. using https://internaldomain.net/dashboard, the link works correctly.

One thought is that the generated URL is formatted improperly so Teams doesn't recognize it or open it. But I can paste it into a browser and it opens properly.

Another thought is that the URL length (almost 500 chars) exceeds some limit for Adaptive Cards, but I haven't been able to find any info about that in the documentation or online.

I would appreciate any other ideas about what might be causing this.

Thanks!

It looks like you're needing to encode the urls before embedding them - probably the {"query" etc. is conflicting with the final Json. It looks like you're using .Net, so you could call WebUtility.UrlEncode, on everything from "?" onwards (i.e. "?overrides...")
