Hi there @shubham ! Thanks for reaching out, and I’m sorry to hear that you’ve run into errors! This error in particular looks like something another learner was experiencing recently: here’s the post for reference. In their case, the routing-url for the accounts subgraph had been published with https rather than http. Could this perhaps be the source of the problem you’re seeing?
If not, please let me know - we can continue troubleshooting to get to the bottom of this!
