No, actually I had to go back and use qrcode v1.5.1 and ngx-qrcode2 v0.0.9 since I can not update the project dependencies It's quite similar to use <ngx-qrcode [qrc-value]="couponCode" [qrc-element-type]="'canvas'" [qrc-class]="'qr-code'"

qrcElement

Finally I solve it with this:

buildOptimizer: true To buildOptimizer: false

In angular.json This worked for me Ref: https://stackoverflow.com/questions/63029367/angular-8-typeerror-cannot-read-property-kind-of-undefined-when-build-my-c
