+I understand you're encountering an error when trying to join the output of the `generate()` function. The error message suggests that the `generate()` function is not returning an iterable object as expected. Let's modify the code to handle this issue:
+
+```python
+def chat_app_logic(message, history):
+    # Your existing code here
+    
+    try:
+        # Attempt to join the generator output
         response = ''.join(generate(
+            model=model,
+            messages=messages,
+            stream=True,
+            temperature=0.7,
+            max_tokens=1500
+        ))
+    except TypeError:
+        # If joining fails, collect the output in a list
+        response_parts = []
+        for part in generate(
+            model=model,
+            messages=messages,
+            stream=True,
+            temperature=0.7,
+            max_tokens=1500
+        ):
+            if isinstance(part, str):
+                response_parts.append(part)
+            elif isinstance(part, dict) and 'content' in part:
+                response_parts.append(part['content'])
+        
+        response = ''.join(response_parts
