503 NullPointerException

My build was successful, now when i was trying to load the Spring boot application i get this error.

I have looked a lot but didn’t find any possible nullpointerexception in portfoliomanagerImpl.getStockQuote.
Also the webpage was not loading.

Hi @vishalbihani2,

Your assigned mentor @ved-prakash-CrioTA will have a call with you today to help you find and resolve the exception. Meanwhile, I’ll recommend you use debugger in each method that is called in the stacktrace of this call to find which variable is going null, as explained previously.

Hi @vishalbihani2

Problem is in static Instance you have taken inside the Portfolio Manager.

Closing this topic as your issue is resolved by the mentor. If it is still not resolved, Kindly un-mark the accepted solution or create a new topic and post this question as a reference link in the description of the new topic.
