Viewing records in playground crashes client about langflow HOT 1 OPEN

The issue you're encountering seems to be related to how the Records Output component handles complex data structures returned by your custom SearXNG component. Specifically, the error message indicates that the component is trying to render an object directly as a React child, which is not allowed.

Here are a few steps to help diagnose and potentially resolve the issue:

1. Check the Data Structure:
   Ensure that the data returned by your SearXNG component is in the expected format. The Records Output component expects an array of records. Each record should be a flat object without nested objects or arrays.

2. Modify the Custom Component:
   If your SearXNG component returns nested objects, you might need to flatten the data before returning it. Here's an example of how you can modify your build method to flatten the data:

   def flatten_dict(d, parent_key='', sep='_'):
       items = []
       for k, v in d.items():
           new_key = f"{parent_key}{sep}{k}" if parent_key else k
           if isinstance(v, dict):
               items.extend(flatten_dict(v, new_key, sep=sep).items())
           else:
               items.append((new_key, v))
       return dict(items)
   
   def build(self, searx_host: str, query: str, num_results: str = 5) -> Record:
       from langchain_community.utilities import SearxSearchWrapper
       s = SearxSearchWrapper(searx_host=searx_host)
       links = s.results(query=query, num_results=num_results)
       flattened_links = [flatten_dict(link) for link in links]
       return Record(links=flattened_links)

3. Update the TableAutoCellRender:
   If you need to handle nested objects or arrays within the cells, ensure that the TableAutoCellRender function is correctly rendering these types. The function should use components like ObjectRender and ArrayReader to handle nested data:

   function getCellType(value) {
       switch (typeof value) {
           case "object":
               if (value === null) {
                   return String(value);
               } else if (Array.isArray(value)) {
                   return <ArrayReader array={value} />;
               } else {
                   return <ObjectRender object={value} />;
               }
           case "string":
               return <StringReader string={value} />;
           case "number":
               return <NumberReader number={value} />;
           default:
               return String(value);
       }
   }

4. Error Handling:
   Ensure that the TableComponent has proper error handling for unexpected or malformed data structures. If the rowData is empty or contains invalid data, it should display an appropriate message instead of crashing:

   if (props.rowData.length === 0) {
       return (
           <div className="flex h-full w-full items-center justify-center rounded-md border">
               <Alert variant={"default"} className="w-fit">
                   <ForwardedIconComponent
                       name="AlertCircle"
                       className="h-5 w-5 text-primary"
                   />
                   <AlertTitle>{alertTitle}</AlertTitle>
                   <AlertDescription>{alertDescription}</AlertDescription>
               </Alert>
           </div>
       );
   }

By ensuring that the data structure is flat and that the rendering functions handle nested objects and arrays correctly, you should be able to prevent the client from crashing when displaying the records output. If the issue persists, you might need to add additional logging or debugging to identify the exact cause of the crash.
