Enable debug logging to see the data that was passed when the pipeline failed.

[96harsh56]

the step that I follow so far is :

1. git clone https://github.com/deepset-ai/haystack.git
2. cd haystack
3. and then docker-compose -f docker-compose.yml pull and then up
   that all and I am getting this error

thankyou for help in advance

Hi @96harsh56! I was not able to replicate this issue. Can it be the case that your docker container doesn't have access to the internet? It seems to fail when trying to download an NLTK resource.
