Input bindings not found while using tool.

Hi everyone,

I’m getting the following error in Copilot Studio when using the “Tool” action connected to my “List Employees” data source:

Destination agent was updated

Input ‘$filter’ has been removed because variable data type not eligible to receive or return values.

Input binding ‘$filter’ is not found, refresh this flow to get the latest bindings.

I’ve tried refreshing the flow and re-selecting the tool, but the error persists. I haven’t found a clear solution in documentation or forums.

This happens in every dataverse tool I create that has Dynamically filled with AI inputs.

Has anyone else encountered this issue or found a workaround?

Thanks in advance!

Hi @NR-24101337-0

It looks to me like the actual input into the Flow itself its not that.

I would publish all customizations on the solution with the flow.

Verify what the inputs actually are into the flow

Refresh your agent

If it still shows that ugg annoying $filter, add another matching nod and rebind to the Flow in the new node. If that work remove this current one.

The schema binding is off so its generating that garbage but without the actual Flow to see I cannot tell you what to type as I do not know your inputs. if you have none, delete that as you do not need it.

If you can share some pictures it will help. But you may also have to delete the Trigger and re-add it, OR you may have to use Save As in your current flow, and point to the newly created one.

Sometimes its just annoying when the metadata is hosed.

If these suggestions help resolve your issue, Please consider Marking the answer as such and also maybe a like.

Thank you!
Sincerely, Michael Gernaey
