Fix HTTP 500 on login and create comprehensive deployment documentation

Browse Source 
CRITICAL FIXES:
- Fixed JWT key configuration issue causing HTTP 500 on login
  - Changed environment variable from JWT_SECRET_KEY to Jwt__Key (double underscore)
  - Increased JWT key length to >32 bytes (256 bits) as required by HMAC-SHA256
  - Fixed ASPNETCORE_URLS configuration (not ASPNETCORE_HTTP_PORTS)

DOCUMENTATION CREATED:
- TROUBLESHOOTING.md: Complete troubleshooting guide with common issues and solutions
- deploy-littleshop.sh: Automated deployment script with working configuration
- docker-compose.hostinger.yml: Docker Compose file with all correct environment variables
- Updated WORKING_BASELINE_2024-09-24.md: Added HTTP 500 fix details

ROOT CAUSES IDENTIFIED:
1. JWT key environment variable naming mismatch (Jwt__Key vs JWT_SECRET_KEY)
2. JWT key too short (was 17 bytes, needs >32 bytes)
3. ASP.NET Core URL configuration issue (ASPNETCORE_URLS vs HTTP_PORTS)
4. Database file permissions (must be owned by UID 1654)

WORKING CONFIGURATION:
- Jwt__Key with 79-byte key
- ASPNETCORE_URLS=http://+:8080
- Proper Docker network configuration (littleshop-network)
- SilverPay integration on port 8000 (not 8001)

This commit ensures we have a stable, documented baseline for future updates
and addresses the concern about "one step forward, two steps back" by
providing comprehensive documentation of all fixes.

# LittleShop Troubleshooting Guide
## Common Issues and Solutions
### 🔴 HTTP 500 Error on Login
#### Symptoms
- Login page loads (HTTP 200)
- Submitting credentials returns HTTP 500
- Error: "Request reached the end of the middleware pipeline"
#### Root Causes & Fixes
##### 1. **JWT Key Configuration Issue**
**Problem**: JWT key environment variable name mismatch or key too short
**Error Message**:
```
IDX10720: Unable to create KeyedHashAlgorithm for algorithm 'http://www.w3.org/2001/04/xmldsig-more#hmac-sha256',
the key size must be greater than: '256' bits, key has '136' bits.
```
**Solution**:
```bash
# CORRECT - Use Jwt__Key (double underscore)
-e Jwt__Key="ThisIsAVeryLongSecretKeyThatIsDefinitelyLongerThan32BytesForSure123456789ABCDEF"
# WRONG - These won't work
-e JWT_SECRET_KEY="..." # Wrong variable name
-e Jwt_Key="..." # Single underscore
-e Jwt__Key="shortkey" # Key too short (< 32 bytes)
```
##### 2. **Parameter Case Sensitivity**
**Problem**: Form sends lowercase but method expected uppercase
**Solution**: Already fixed in code - Login method now accepts both cases:
```csharp
public async Task<IActionResult> Login(string Username, string Password)
{
var username = Username?.ToLowerInvariant();
var password = Password;
// ...
}
```
##### 3. **Port Configuration Issue**
**Problem**: App listening on wrong port
**Solution**:
```bash
# CORRECT
-e ASPNETCORE_URLS="http://+:8080"
# WRONG
-e ASPNETCORE_HTTP_PORTS=8080 # This doesn't work
```

### 🔴 Container Shows "Unhealthy"
#### Symptoms
- Container running but marked as unhealthy
- Health check failing
#### Solution
1. The health check includes database check which can timeout during initialization
2. App still works even if marked unhealthy
3. To disable health check issues, run without health check or increase timeout
---
### 🔴 Database Permission Errors
#### Symptoms
- SQLite Error 8: attempt to write a readonly database
- Cannot create or update database
#### Solution
```bash
# Database MUST be owned by UID 1654
sudo chown -R 1654:1654 /opt/littleshop/data/
```
---
### 🔴 Network Connectivity Issues
#### Symptoms
- Containers can't communicate
- SilverPay API unreachable
- "Name or service not known" errors
#### Solution
```bash
# All containers must be on littleshop-network
docker network connect littleshop-network littleshop-admin
docker network connect littleshop-network silverpay-api
docker network connect littleshop-network nginx-proxy-manager
```
---
### 🔴 Anti-forgery Token Validation Errors
#### Symptoms
- 400 Bad Request on form submissions
- CSRF token validation failures
#### Current Status
- Anti-forgery validation is temporarily disabled on login
- This is noted in the code: `// [ValidateAntiForgeryToken] // Temporarily disabled for HTTPS proxy issue`
---
## Quick Diagnostics
### Check Container Status
```bash
docker ps --format "table {{.Names}}\t{{.Status}}" | grep littleshop
```
### Check Logs for Errors
```bash
docker logs littleshop-admin --tail 50 | grep -E "Exception|ERROR|fail"
```
### Test Login Locally
```bash
docker exec littleshop-admin curl -X POST http://localhost:8080/Admin/Account/Login \
-d "Username=admin&Password=admin" \
-o /dev/null -w "Status: %{http_code}\n"
```
### Check Environment Variables
```bash
docker exec littleshop-admin printenv | grep -E "Jwt|ASPNETCORE"
```
---
## Recovery Procedures
### Complete Reset
```bash
# Stop everything
docker stop littleshop-admin
docker rm littleshop-admin
# Clean up
sudo rm -rf /opt/littleshop/data/*
# Fix permissions
sudo mkdir -p /opt/littleshop/{data,logs,uploads}
sudo chown -R 1654:1654 /opt/littleshop/data/
# Redeploy
./deploy-littleshop.sh
```
### Emergency Development Mode
To see detailed errors:
```bash
docker run -d \
--name littleshop-admin \
--network littleshop-network \
-p 127.0.0.1:5100:8080 \
-v /opt/littleshop/data:/app/data \
-e ASPNETCORE_ENVIRONMENT=Development \
-e ASPNETCORE_URLS="http://+:8080" \
-e ConnectionStrings__DefaultConnection="Data Source=/app/data/littleshop-production.db" \
-e Jwt__Key="ThisIsAVeryLongSecretKeyThatIsDefinitelyLongerThan32BytesForSure123456789ABCDEF" \
littleshop:latest
```
---
## Critical Configuration Points
### Must-Have Environment Variables
```
ASPNETCORE_ENVIRONMENT=Production
ASPNETCORE_URLS=http://+:8080 # NOT HTTP_PORTS!
Jwt__Key=[minimum 32 bytes] # Double underscore!
ConnectionStrings__DefaultConnection=Data Source=/app/data/littleshop-production.db
```
### Required Docker Network
```
littleshop-network (external)
```
### Required Permissions
```
/opt/littleshop/data: UID 1654
/opt/littleshop/logs: UID 1654
/opt/littleshop/uploads: UID 1654
```
