Could you let me know what version of Semantic Kernel you are using? Something might have changed in the new versions. I'll take a look at this over the weekend.

Also, the Ollama Plugin will soon be integrated into the main repository of semantic kernel. You can check out here. Some minor work is pending, hopefully, it gets merged into main soon

Thank you for getting back to me! I have the following packages installed

Try changing your builder.AddOllamaTextGeneration to builder.AddOllamaChatCompletion. I had the same error the first time I tried.

@descention - This worked for me! Thank you!

builder. AddOllamaTextGeneration should also work; I have pushed version 1.3.1 of the plugin that I tested against semantic kernel 1.14.1; let me know if it works for you.
