Hello @weiwenyan-dev! I'm here to assist you with any bugs, questions, or contributions you have for Dify. Let me know how I can help!

The issue you're experiencing with the front-end page not rendering correctly when the workflow output panel is a text output type and the result is an array of strings is due to the isTextOutput condition only checking for a single string. This condition does not account for arrays of strings, which prevents the rendering logic for text output from being triggered.

To fix this, you need to modify the isTextOutput condition to handle arrays of strings. You can update the condition to check if the output is an array and if all elements are strings, then join them into a single string for rendering. Here's how you can adjust the code:

const isTextOutput = useMemo(() => {
  if (!outputs || Object.keys(outputs).length !== 1) return false;
  const outputValue = outputs[Object.keys(outputs)[0]];
  return typeof outputValue === 'string' || 
         (Array.isArray(outputValue) && outputValue.every(item => typeof item === 'string'));
}, [outputs]);

And modify the rendering logic to handle arrays:

{isTextOutput && (
  <div className='px-4 py-2'>
    <Markdown content={Array.isArray(outputs[Object.keys(outputs)[0]]) 
      ? outputs[Object.keys(outputs)[0]].join('\n') 
      : outputs[Object.keys(outputs)[0]] || ''} />
  </div>
)}

This change ensures that arrays of strings are treated as text output and rendered correctly ^[1].

What do you mean I found out about it myself and figured out how to fix it by submitting an issue first and then submitting the merge request
