fix: prevent import-time initialization of chat service

Browse files

- Add version marker to track deployment updates
- Use lazy initialization for chat_service to avoid creating agents at import
- Add get_chat_service() factory function
- Wrap chat_service import in try/except to handle errors gracefully

This should finally fix the CommunicationAgent abstract method error

+ # 🚨 Correção Urgente - Backend HuggingFace
2
+
3
+ ## Problema Identificado
4
+
5
+ O backend no HuggingFace estΓ‘ rodando a versΓ£o **ERRADA** do cΓ³digo:
6
+
7
+ 1. **VersΓ£o atual** (app.py): Apenas tem o EnhancedZumbiAgent
8
+ 2. **VersΓ£o correta** (src/api/app.py): Sistema completo com Drummond e todos os agentes
9
+
10
+ Por isso o frontend sempre retorna "modo manutenΓ§Γ£o" - o Drummond nΓ£o existe!
11
+
12
+ ## SoluΓ§Γ£o Imediata
13
+
14
+ ### OpΓ§Γ£o 1: Substituir app.py (Mais Simples)
15
+
16
+ ```bash
17
+ # No branch hf-fastapi
18
+ git checkout hf-fastapi
19
+
20
+ # Backup do app.py atual
21
+ mv app.py app_simple.py
22
+
23
+ # Criar novo app.py que importa o sistema completo
24
+ cat > app.py << 'EOF'
25
+ #!/usr/bin/env python3
26
+ import os
27
+ import sys
28
+ sys.path.insert(0, os.path.dirname(os.path.abspath(__file__)))
29
+
30
+ from src.api.app import app
31
+ import uvicorn
32
+
33
+ if __name__ == "__main__":
34
+ port = int(os.getenv("PORT", 7860))
35
+ uvicorn.run(app, host="0.0.0.0", port=port, forwarded_allow_ips="*", proxy_headers=True)
36
+ EOF
37
+
38
+ # Commit e push
39
+ git add app.py app_simple.py
40
+ git commit -m "fix: use full multi-agent system with Drummond in HuggingFace deployment"
41
+ git push origin hf-fastapi
42
+ ```
43
+
44
+ ### OpΓ§Γ£o 2: Adicionar Drummond ao app.py Atual
45
+
46
+ Se preferir manter o app.py simplificado, adicione o Drummond:
47
+
48
+ ```python
49
+ # No app.py, apΓ³s a linha 522 (onde cria enhanced_zumbi):
50
+ from src.agents.drummond_simple import SimpleDrummondAgent
51
+ drummond_agent = SimpleDrummondAgent()
52
+
53
+ # Adicionar endpoint do Drummond
54
+ @app.post("/api/v1/chat/message")
55
+ async def chat_message(request: ChatRequest):
56

+ ## CorreΓ§Γ£o do Erro 403 da API
76
+
77
+ O erro 403 indica que a API key do Portal da TransparΓͺncia estΓ‘ invΓ‘lida:
78
+
79
+ 1. Verifique no HuggingFace Spaces Settings:
80
+ - VΓ‘ para: https://huggingface.co/spaces/neural-thinker/cidadao.ai-backend/settings
81
+ - Procure por `TRANSPARENCY_API_KEY`
82
+ - Se nΓ£o existir ou estiver invΓ‘lida, adicione uma nova
83
+
84
+ 2. Para obter nova API key:
85
+ - Acesse: https://www.portaldatransparencia.gov.br/api-de-dados
86
+ - Cadastre-se e gere uma nova chave
87
+ - Adicione no HuggingFace Spaces
88
+
89
+ ## Deploy Correto
90
+
91
+ ```bash
92
+ # ApΓ³s fazer as correΓ§Γ΅es
93
+ git push origin hf-fastapi
94
+
95
+ # O HuggingFace deve fazer redeploy automΓ‘tico
96
+ # Se nΓ£o, vΓ‘ em Settings > Factory reboot
97
+ ```
98
+
99
+ ## VerificaΓ§Γ£o
100
+
101
+ ApΓ³s o deploy, teste:
102
+
103
+ ```bash
104
+ # Verificar se Drummond estΓ‘ disponΓ­vel
105
+ curl https://neural-thinker-cidadao-ai-backend.hf.space/api/v1/chat/message \
106
+ -H "Content-Type: application/json" \
107
+ -d '{"message": "OlΓ‘, como vocΓͺ pode me ajudar?"}'
108
+
109
+ # Deve retornar resposta do Drummond, nΓ£o "modo manutenΓ§Γ£o"
110
+ ```
111
+
112
+ ## Resumo
113
+
114
+ 1. **Problema**: VersΓ£o errada deployada (sem Drummond)
115
+ 2. **SoluΓ§Γ£o**: Usar app.py que importa src.api.app completo
116
+ 3. **Extra**: Corrigir API key do Portal da TransparΓͺncia
117
+ 4. **Resultado**: Frontend funcionarΓ‘ normalmente com chat ativo
