.Net: Get Method missing in Handlebars planner to parse JSON output

[rithvikb23]

When using the Handlebars planner in semantic kernel, I noticed an issue when the planner was parsing the actual JSON output. For example: I have an API that calculates the price target for a given stock ticker. This API is documented in an OpenAPI spec. After loading the spec as a plugin using the ImportPluginFromOpenApiAsync method and asking the query "what is the price target of GOOGL" the planner produces this plan:

**Original plan:
{{!-- Step 1: Set the ticker symbol for which the price target is to be retrieved --}}
{{set "ticker" "GOOGL"}}

{{!-- Step 2: Use the custom helper to retrieve the price target for the specified ticker symbol --}}
{{set "priceTarget" (PriceTargetPlugin-getPriceTarget Ticker=ticker)}}

{{!-- Step 3: Output the result --}}
{{json (concat "The price target of " ticker " is: $" priceTarget)}}

Result:
The price target of GOOGL is: ${"value":180}**

The problem in the result is that the json helper is not getting the actual value, instead it is returning the actual json object.

Ideally it should look like: The price target of GOOGL is 180. I am using Semantic Kernel 1.0.1 in .NET 6.

Is there a setting allow getting the actual value, I have attempted to tweak the response section of my OpenAPI spec but it is still not retrieving the exact value.

Isn't this the same as this one: #4596 ".Net: get helper needs to be added back to the handlebars planner #4596"?
(found this after being mentioned during yesterday's Office Hours)

This appears to be a different issue than #4596. I think the real issue is that we are not including the response schema for custom helpers in the handlebars prompt template, so the planner does not know how to parse data out of the response object. I am working on a fix for this.
