For Context please check #29626 The Deepseek is using langchain_openai. The error happens that it show `json decode error`. I added a handler for this to give a more sensible error message which is DeepSeek API returned empty/invalid json. Reproducing the issue is a bit challenging as it is inconsistent, sometimes DeepSeek returns valid data and in other times it returns invalid data which triggers the JSON Decode Error. This PR is an exception handling, but not an ultimate fix for the issue. --------- Co-authored-by: Chester Curme <chester.curme@gmail.com> |
