frxjs/ngx-timeline 'cannot assign to read only property of object' errors

I am using angular 16 and I installed npm I @frxjs/ngx-timeline@17.0.10. My company has its own artifactory and I uploaded the timeline Library to there after changing the dependency from angular 16 to 17.

I get this error: " Cannot assign to read only property 0 of object [object array]
