Error: Null is causing an issue and preventing property 'isSkipSelf' from being read in Angular7

While assembling the package for my module, I encountered the following error.

TypeError: Cannot read property 'isSkipSelf' of null at ProviderElementContext._getDependency(C:\Users\ravinder\MyProjectName\node_modules\@angular\compiler\bundles\compiler.umd.js:19242:22

I have attempted various solutions found online such as checking for missing @injectable, verifying dependency injection, handling circular dependencies, and more. Any assistance on this matter would be greatly appreciated.

Answer №1

After some troubleshooting, I was able to identify the root cause of the issue. It turned out that there were two faulty imports causing the problem. One import had an extra forward slash at the end of the path, while the other import pointed to a folder instead of a TypeScript file. Surprisingly, TypeScript Compiler did not generate any error messages for these incorrect imports.

Answer №2

If your code appears to be correct, the issue may stem from problems with your node modules. Give this a try:

  npm install

After installing the necessary packages, attempt to build the library again; this should resolve most issues.
