Getting error while trying to use "Summarize_Conversation" plugin of Semantic Kernel

[KSHAMIN]

Hi everyone,
I am getting the following error while trying to use "Summarize_Conversation" plugin of semantic kernel (https://learn.microsoft.com/en-us/semantic-kernel/prompts/calling-nested-functions?tabs=python)

User:> hi Error rendering code block: maximum recursion depth exceeded Error invoking function ConversationSummaryPlugin.SummarizeConversationError rendering code block: Error invoking functionConversationSummaryPlugin.SummarizeConversationError invoking functionConversationSummaryPlugin.SummarizeConversationError rendering code block: Error invoking functionConversationSummaryPlugin.SummarizeConversationError invoking functionConversationSummaryPlugin.SummarizeConversationError rendering code block: Error invoking functionConversationSummaryPlugin.SummarizeConversationError invoking functionConversationSummaryPlugin.SummarizeConversationError rendering code block: Error invoking functionConversationSummaryPlugin.SummarizeConversationError invoking functionConversationSummaryPlugin.SummarizeConversationError rendering code block: Error invoking functionConversationSummaryPlugin.SummarizeConversationError invoking functionConversationSummaryPlugin.SummarizeConversationError rendering code block: Error invoking functionConversationSummaryPlugin.SummarizeConversation`

Something went wrong in function invocation. During function invocation: 'Summarize_Conversation-Chat'. Error description: 'Error rendering code block: Error invoking function ConversationSummaryPlugin.SummarizeConversation'

It would be really great if someone could help me with this!
