CreatePlan fails with InsufficientFunctionsForGoal

[mrochon]

I am using your C# code for planner sample and getting the following exception. What am I missing?

System.AggregateException
HResult=0x80131500
Message=One or more errors occurred. ([InsufficientFunctionsForGoal] Unable to create plan for goal with available functions.
Goal: Check the weather in Guangzhou, use spanish to write emails abount dressing tips based on the results
Available Functions: CompanySearchPlugin-EmployeeSearch, CompanySearchPlugin-WeatherSearch
Planner output:
To achieve the goal of checking the weather in Guangzhou and using Spanish to write emails about dressing tips, follow these steps using the available helpers:

1. Set the location to "Guangzhou" using the {{set}} helper:

{{set "location" "Guangzhou"}}

2. Use the CompanySearchPlugin-WeatherSearch helper to search for the weather in the specified location:

{{set "weatherResult" (CompanySearchPlugin-WeatherSearch text=location)}}

3. Determine the dressing tips based on the weather result using an {{#if}} statement:

{{#if (equals weatherResult "sunny")}}
  {{set "dressingTips" "Use sunscreen and wear a hat."}}
{{else if (equals weatherResult "rainy")}}
  {{set "dressingTips" "Carry an umbrella and wear waterproof shoes."}}
{{else if (equals weatherResult "cloudy")}}
  {{set "dressingTips" "Bring a light jacket, just in case."}}
{{else}}
  {{set "dressingTips" "Additional helpers may be required"}}
{{/if}}

4. Use the {{json}} helper to output the dressing tips in Spanish:

{{json (concat "Consejos de vestuario: " dressingTips)}}

Putting it all together, the complete Handlebars template would look like this:

{{!-- Step 1: Set the location --}}
{{set "location" "Guangzhou"}}

{{!-- Step 2: Search for weather --}}
{{set "weatherResult" (CompanySearchPlugin-WeatherSearch text=location)}}

{{!-- Step 3: Determine dressing tips based on weather --}}
{{#if (equals weatherResult "sunny")}}
  {{set "dressingTips" "Use sunscreen and wear a hat."}}
{{else if (equals weatherResult "rainy")}}
  {{set "dressingTips" "Carry an umbrella and wear waterproof shoes."}}
{{else if (equals weatherResult "cloudy")}}
  {{set "dressingTips" "Bring a light jacket, just in case."}}
{{else}}
  {{set "dressingTips" "Additional helpers may be required"}}
{{/if}}

{{!-- Step 4: Output dressing tips in Spanish --}}
{{json (concat "Consejos de vestuario: " dressingTips)}}
```)

Have you registered all relevant plugins? In the example, it is mentioned that the relevant plug-ins must be registered first

[mrochon]

Same as in your sample (I think; LoadPlugins is my own extension)
kernel.LoadPlugins("WriterPlugin", "EmailPlugin", "TranslatePlugin");
var companySearchPluginObj = new CompanySearchPlugin();
var companySearchPlugin = kernel.ImportPluginFromObject(companySearchPluginObj, "CompanySearchPlugin");

[kinfey]

can you send me your code ?
