🔧 Fix: Agent Chat Send Button Now Works

Problem Identified

After clicking "Chat with Selected Agent", the chat textbox enabled correctly, but when sending a message, users received the error:

⚠️ No agent configuration found. Please Generate or Load an agent first.

Root Cause

Three more functions were still using the global agents_config dictionary instead of per-user session storage:

1. builderpanel_handle_with_dynamic_vars() - Handles messages in builder panel
2. chatpanel_handle_with_dynamic_vars() - Handles messages in deployed chat panel
3. update_dynamic_vars_visibility() - Shows/hides dynamic fields based on agent skills

# OLD (Broken after isolation):
def builderpanel_handle_with_dynamic_vars(agent_name, user_text, histories, ...):
    agent_json = agents_config.get(agent_name)  # ❌ Global storage - returns None

Since agents are now stored per-user, the global dictionary was empty, causing agent_json to be None, which triggered the "No agent configuration found" error in the chat orchestrator.

Solution Applied

Updated all three functions to use per-user agent storage:

1. builderpanel_handle_with_dynamic_vars (Builder Panel Chat)

# NEW (Fixed):
def builderpanel_handle_with_dynamic_vars(
    agent_name, user_text, histories,
    ...,
    request: gr.Request  # ✅ Added
):
    agent_json = get_user_agent(request, agent_name)  # ✅ Per-user storage

Changes:

• Added request: gr.Request parameter
• Replaced 2 instances: agents_config.get(agent_name) → get_user_agent(request, agent_name)

2. chatpanel_handle_with_dynamic_vars (Deployed Chat Panel)

# NEW (Fixed):
def chatpanel_handle_with_dynamic_vars(
    agent_name, user_text, histories,
    ...,
    request: gr.Request  # ✅ Added
):
    agent_json = get_user_agent(request, agent_name)  # ✅ Per-user storage

Changes:

• Added request: gr.Request parameter
• Replaced 2 instances: agents_config.get(agent_name) → get_user_agent(request, agent_name)

3. update_dynamic_vars_visibility (Dynamic Fields)

# NEW (Fixed):
def update_dynamic_vars_visibility(agent_name, request: gr.Request):
    agent_json = get_user_agent(request, agent_name)  # ✅ Per-user storage

Changes:

• Added request: gr.Request parameter
• Replaced: agents_config.get(agent_name) → get_user_agent(request, agent_name)

4. Agent Picker Dropdown Initial State

# OLD:
agent_picker = gr.Dropdown(
    choices=list(agents_config.keys()),  # ❌ Global storage
)

# NEW:
agent_picker = gr.Dropdown(
    choices=[],  # ✅ Empty, populated per-user by refresh_chat_dropdown
)
