I am novice in Flowise/Railway

I am trying to test a template of a chatflow called

Conversational Retrieval QA Chain

I applied API and credentials,

But some errors occured:

" Request failed to reach Pinecone. This can occur for reasons such as incorrect configuration (environment, project id, index name), network problems that prevent the request from being completed, or a Pinecone API outage. Check your client configuration, check your network connection, and visit

https://status.pinecone.io/

to see whether any outages are ongoing."
