Asked on May 02, 2018
I am using "angular-in-memory-web-api": "^0.6.0".  When I run the application, I am getting 500 internal server error in browser console.
Find the stack trace.

ERROR {…}?body: Object { error: "Object(...) is not a function" }?headers: Object { normalizedNames: Map, lazyUpdate: null, lazyInit: lazyInit() }?status: 500?

statusText: "Internal Server Error"?url: "/api/users"?__proto__: Object { … } core.js:1665:5

angular-in-memory-web-api   version 0.6.0 works with RxJS v6

Check your RxJS version in package.json

You can solve your error by using angular-in-memory-web-api   version 0.5.4

Use following command:

npm uninstall angular-in-memory-web-api --save

npm i [email protected] --save

Reference:


0.6.0 (2018-03-22)

Migrate to Angular v6 and RxJS v6

Note that this release is pinned to Angular "^6.0.0-rc.0" and RxJS "^6.0.0-beta.1". Will likely update again when they are official.

BREAKING CHANGE This version depends on RxJS v6 and is not backward compatible with earlier RxJS versions.
