TypeError: Cannot read property 'kind' of undefined at getAssignmentTargetKind

Question

This problem started to occur when updating my Angular 6 project to 7.x.

I opened an issue on the angular-cli github repo but they couldn't help.

So what I did is create a new project and add all components one by one to "hopefully" notice what caused the problem.

Unfortunately I couldn't identify the problem. Here's the log:

ERROR in : TypeError: Cannot read property 'kind' of undefined at getAssignmentTargetKind (E:\McClient\node_modules\typescript\lib\typescript.js:10049:28) at Object.isAssignmentTarget (E:\McClient\node_modules\typescript\lib\typescript.js:10092:16) at checkObjectLiteral (E:\McClient\node_modules\typescript\lib\typescript.js:46107:45) at checkExpressionWorker (E:\McClient\node_modules\typescript\lib\typescript.js:50748:28) at checkExpression (E:\McClient\node_modules\typescript\lib\typescript.js:50696:42) at checkExpressionWithContextualType (E:\McClient\node_modules\typescript\lib\typescript.js:50524:26) at checkApplicableSignature (E:\McClient\node_modules\typescript\lib\typescript.js:47963:35) at chooseOverload (E:\McClient\node_modules\typescript\lib\typescript.js:48281:26) at resolveCall (E:\McClient\node_modules\typescript\lib\typescript.js:48231:26) at resolveCallExpression (E:\McClient\node_modules\typescript\lib\typescript.js:48534:20) at resolveSignature (E:\McClient\node_modules\typescript\lib\typescript.js:48800:28) at getResolvedSignature (E:\McClient\node_modules\typescript\lib\typescript.js:48844:26) at checkCallExpression (E:\McClient\node_modules\typescript\lib\typescript.js:48936:29) at checkExpressionWorker (E:\McClient\node_modules\typescript\lib\typescript.js:50759:28) at checkExpression (E:\McClient\node_modules\typescript\lib\typescript.js:50696:42) at resolveDecorator (E:\McClient\node_modules\typescript\lib\typescript.js:48741:28) 

Here's a link to the github issue with logs from a checkSourcefile function I was supposed to log:

How can I track down and (hopefully) fix what's causing this?

Edit: My ng --version info

I simply re-run

    ng serve 

again and it worked!
