Hi @aleksandra_budnik.
Correct me if I am wrong.
Now I have to install handsontable. There is no such thing as handsontable-pro.
We have to make changes in my angular project like instead of importing from handsontable-pro to Handsontable.
eg: Earlier we used to write
import { HotTableModule, HotTableRegisterer } from ‘@handsontable-pro/angular’;
for settings.colHeaders.length = 0;
Property ‘length’ does not exist on type ‘true | string[] | ((index: number) => string)’.
Property ‘length’ does not exist on type ‘true’.
Although I have an array of string for colHeaders.
Here Angular (forked) - StackBlitz is an example of an angular (wrapper) + Handsontable 7.0.0 project. Please check if your configuration follows this pattern. If that won’t help please share a demo where this issue can be replicable. It can be a .zip as well. If you do not want to share it here please send it to support@handsontable.com
