+    @Bean
+    public CorsConfigurationSource corsConfigurationSource() {
+        CorsConfiguration configuration = new CorsConfiguration();
+        configuration.addAllowedOriginPattern("*"); // Allow all origins in development


Allowing all origins with wildcard pattern '*' in CORS configuration poses a security risk. Consider restricting to specific origins or implementing environment-based configuration that limits origins in production.

Suggested change

configuration.addAllowedOriginPattern("*"); // Allow all origins in development

// Restrict origins based on environment

String[] activeProfiles = environment.getActiveProfiles();

boolean isDev = false;

for (String profile : activeProfiles) {

if ("dev".equalsIgnoreCase(profile) || "development".equalsIgnoreCase(profile)) {

isDev = true;

break;

}

}

if (isDev) {

configuration.addAllowedOriginPattern("*"); // Allow all origins in development

log.info("CORS: Allowing all origins (development mode)");

} else {

// TODO: Replace with your actual production frontend origin(s)

configuration.setAllowedOrigins(List.of("https://your-frontend-domain.com"));

log.info("CORS: Restricting origins to production frontend(s)");

}

+                <div className="bg-gray-50 p-4 rounded-lg">
+                  <div className="grid grid-cols-1 md:grid-cols-3 gap-4 text-sm">
+                    <div>
+                      <span className="font-medium text-gray-700">Chunk ID:</span>


The code references 'contentData.chunkId' and 'contentData.fileType' but the GetContentResponse type in api.ts doesn't include these fields. This will cause runtime errors when trying to access undefined properties.

+                    <div>
+                      <span className="font-medium text-gray-700">Tokens:</span>
+                      <div className="text-gray-600">
+                        {contentData.tokenInfo.tokenCount} / {maxTokens}


The tokenInfo object is being accessed with 'tokenCount' property, but according to the GetContentResponse type, it should be 'actualTokens'.

Suggested change

{contentData.tokenInfo.tokenCount} / {maxTokens}

{contentData.tokenInfo.actualTokens} / {maxTokens}

+    case 'DELETING':
+      return 'text-secondary-600 bg-secondary-50'
+    default:
+      return 'text-secondary-600 bg-secondary-50'


The color classes 'text-success-600', 'bg-success-50', etc. are not standard Tailwind CSS classes. These should use standard Tailwind color names like 'text-green-600', 'bg-green-50' to ensure the styles are applied correctly.

Suggested change

return 'text-secondary-600 bg-secondary-50'

return 'text-green-600 bg-green-50'

case 'ERROR':

return 'text-red-600 bg-red-50'

case 'PENDING':

return 'text-yellow-600 bg-yellow-50'

case 'PARSING':

case 'CHUNKING':

case 'EMBEDDING':

case 'INDEXING':

return 'text-blue-600 bg-blue-50'

case 'DELETING':

return 'text-gray-600 bg-gray-50'
