Hey Folks

I am trying to deploy agents to the Test environment and gettign the following error.

{
  "statuscode":500,
  "statusdescription":"Internal Server Error",
  "errors":[
    {
      "code":10000,
      "message":"The given key was not present in the dictionary."
    }
  ]
}

Impact:

Deployment to the test environment is blocked.
The agent cannot be validated or tested prior to production deployment.
Testing timelines and downstream integrations may be delayed.

Any pointers pls

Hi Bro,

Can i check what knowledge sources are being used. Are you using any Dataverse table (or) Custom Prompt (Ai builder) that uses the table values?

If not, mostly this error can happen only because of connections. Can you check if any configuration field or environment variable is missing? Since this is a .NET style exception, i think some variable or connection is missing.

I also read another query where they asked to verify the language settings also. Set as Default English language and try again.

Thanks.

Hi @ragavanrajan, were you able to fix this?

I'm trying to move an agent thru environments using pipelines and I have the same issue. If I export the solution and import it manually, it works without issue.
