[Question]: Error: 'list' object has no attribute 'get' when using the preview window conversation function of the chat API

[metasavvy]

Describe your problem

api/apps/api_app.py

def rename_field(ans):
for chunk_i in ans['reference'].get('chunks', []):
chunk_i['doc_name'] = chunk_i['docnm_kwd']
chunk_i.pop('docnm_kwd')

Ans ['reference '] needs to be typed, otherwise an exception will be thrown (' list 'object has no attribute' get ')

@metasavvy @KevinHuSh
metasavvy 所以怎么才能解决，我拉取最新代码还是不行。要重新拉镜像吗？我去看你们的历史版本，也没有说修复了#1690的bug呀
so how to solve this problem? i have pulled the newest ragflow codes but it still doesn't works. do you mean that you will fix it in the next version?

@zzlTim Try this one.
Router /completion of /api/apps/api_app.py:
If the 'stream' param is passed as True, add some lines to the rename_field funtion

def rename_field(ans):
          # print(ans['reference'], flush=True)
          if isinstance(ans['reference'], list):
              temp = ans['reference'][::1]
              ans['reference'] = {
                  'chunks': temp
              }
          for chunk_i in ans['reference'].get('chunks', []):
              chunk_i['doc_name'] = chunk_i['docnm_kwd']
              chunk_i.pop('docnm_kwd')

And if the 'stream' param is passed as False, add some lines to the other case as above

if req.get("stream", True):
          resp = Response(stream(), mimetype="text/event-stream")
          resp.headers.add_header("Cache-control", "no-cache")
          resp.headers.add_header("Connection", "keep-alive")
          resp.headers.add_header("X-Accel-Buffering", "no")
          resp.headers.add_header("Content-Type", "text/event-stream; charset=utf-8")
          return resp
      else:
          answer = None
          for ans in chat(dia, msg, **req):
              answer = ans
              fillin_conv(ans)
              API4ConversationService.append_message(conv.id, conv.to_dict())
              break
          if isinstance(answer['reference'], list):
              temp = answer['reference'][::1]
              answer['reference'] = {
                  'chunks': temp
              }
          for chunk_i in answer['reference'].get('chunks',[]):
              chunk_i['doc_name'] = chunk_i['docnm_kwd']
              chunk_i.pop('docnm_kwd')

          return get_json_result(data=answer)
