Hi all,
I'm hoping someone has seen this. The Copilot Studio Kit (Copilot Agent Kit, version 20260608.1) Agent Review Tool opens to a completely blank white screen in one of my Dataverse environments. The exact same tool, same Kit version, works perfectly in another environment in the same tenant. It's not only the Agent Review Tool – Agent Inventory and even the Setup Wizard's "Activate Flows" step are also blank in that environment.
When I inspect the page, the app shell loads but the React root (<div id="root">) stays empty – nothing renders into it. There is a console warning "React.createElement: type is invalid … got: undefined", but that same warning also appears in my WORKING environment where the screen renders fine, so it doesn't seem to be the cause.
Digging further, I found what looks like the real underlying problem. The screens that are blank all depend on the Kit's cloud flows, and in the failing environment those flows are not activated. Two concrete errors:
1. Agent Inventory shows:- "UnpublishedSolutionFlowCannotBeInstalled – An unpublished solution flow cannot be installed. Please turn on the flow to enable activation."
2. When I try to turn the flows on manually (GrandChild → Child → parent order, as the wizard instructs), I get:
"The connection ID is missing for the logical name 'cat_CopilotStudioAcceleratorPowerPlatformforAdmins' for the connection reference."
So it seems the flows can't activate because a connection reference isn't bound – and the Setup Wizard step that would normally fix this is itself blank, which leaves me stuck in a loop.
Things I've already checked / ruled out:
- Solution versions – updated and aligned across both environments.
- Admin settings – "Allow publishing of canvas apps with code components" and "Enable code apps" are ON in both environments.
- Network – all app resources load with HTTP 200; only Microsoft telemetry (*.data.microsoft.com) was blocked and our network team has since allowed it through the proxy. No change.
- Browser – reproduced in Incognito with all extensions disabled.
- Environment variables – compared both environments and corrected the Instance Url (was a placeholder).
- The user performing this has the System Administrator role.
My questions:
1. How can I bind the missing connection reference and activate the Kit's flows when the Setup Wizard UI that normally does this is itself rendering blank?
2. Is a blank Agent Review Tool / Agent Inventory a known result of an interrupted or incomplete first-time Setup Wizard run, and what's the recommended way to recover an environment in this state?
3. Is this a known issue with Kit build 20260608.1 specifically?
Any pointers appreciated – happy to share more detail. Thanks!
