Angular's new http client error Cannot read property 'data' of undefined

Question

I am learning how to use angular\'s new http client module. I get the error Cannot read property \'data\' of undefined when I try to consume the rest api. Here\'s my app.htm

Answer 1

Cannot read property 'data' of undefined simply means that results in not defined. Put console.log or apply breakpoints and try to find out why its not getting defined. When we apply breakpoints we can find out the exact reasons why it is not getting defined. Knowing the reason is important.
