Hi
I am trying to install firecrawl and I this error message “Error loading package “@mendable/n8n-nodes-firecrawl” :Checksum verification failed.”
Using perplexity to resolve this issue it provides me with this root cause
Root Cause
n8n Cloud uses an internal Verdaccio registry (verdaccio.n8n-verdaccio.svc.cluster.local) to host/verify community nodes like @mendable/n8n-nodes-firecrawl. The checksum verification fails due to an internal DNS resolution problem (getaddrinfo ENOTFOUND) or metadata sync issue, preventing the package download even if it’s valid on npm.
Describe the problem/error/question
I am unable to install FIrecrawl
What is the error message (if any)?
“Error loading package “@mendable/n8n-nodes-firecrawl” :Checksum verification failed. Please check your network connection and try again.”
Please share your workflow
