encoder error

[kevin-liu-astrumu]

here is the bug report when I feed input as a string to extract entities

response = self.chain.predict_and_parse(text=text)
File "/Users/kevinliu/opt/anaconda3/envs/s3demo/lib/python3.9/site-packages/langchain-0.0.235-py3.9.egg/langchain/chains/llm.py", line 281, in predict_and_parse
return self.prompt.output_parser.parse(result)

Use .run instead of predict and parse method with the newest kor version (0.13.0)

[mandar-karhade]

run leaves the tags while predict_and_parse provides correct output. Is there a separate parse procedure after chain.run()?

@mandar-karhade could you provide an example of what you mean? Which version of langchain are you using?
