When publish, it failed and saying the error due to invalidPropertyPath.

PropertyName : " PropertyName"

in the output, there is no "PropertyName" listed and in the sharepoint List also. But why this hidden parameter showing?

The invalidPropertyPath error with "PropertyName" usually means your Copilot Studio agent or Power Automate flow is referencing a property (field/column) that does not exist in your SharePoint List or in the connector output.

Why does this happen?

Sometimes, a property is referenced in your agent logic, topic, or flow (e.g., as a variable or in a data mapping), but it was deleted or renamed in SharePoint.

The property may be hidden, misspelled, or leftover from a previous configuration.

The error can also occur if a dynamic field is expected but not present in the response.

How to fix:

Check all mappings: Review your agent, topic, and flow for any references to "PropertyName".

Remove or update references: Delete or update any mapping, variable, or action that uses this property.

Refresh schema: In Copilot Studio or Power Automate, refresh the SharePoint connector schema to ensure all fields are up to date.

Republish: Try publishing again after making these changes.

I have same problem, but there is not topic or flow calling the ExAgent, the ExAgent is a child agent, and i found out that once removed the input variables, we are not longer receive the error, but we need to have the input varible set. is this a bug?

"diagnosticResult": [
{
"$kind": "PropertyError",
"propertyName": "PropertyName",
"errorCode": "InvalidPropertyPath",
"errorMessage": "The specified property path for 'PropertyName' is invalid
or does not exist in the target object."
}
],
"componentDisplayName": "ExAgent",
