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

TypeScript Version: 3.2.2

Search Terms: Cannot read property ‘kind’ of undefined

I have found some results about this error but I haven’t found anything about the problem where my project throws the error: “at getAssignmentTargetKind”

Code I’m using angular 7.2.0 - the error first occured when I updated from 6.x to 7.x. Also I tried creating a new project and just migrate everything file by file but since the error happens so randomly it’s almost impossible to track down the file causing the problem 😕

Here’s the full error message:

I added this to typescript.js:

function getAssignmentTargetKind(node) {
        var parent = node.parent;

        if(!parent) {
          console.log(node)
        }

Here’s the console.log

Expected behavior: No errors

Actual behavior: See above

Is there anything I can do to finally track down the file/code causing the error?
