I have the same issue on my project. We are using ngx-charts-pie-chart. In my case the problem is when there is an attempt to animate <svg> elements. We tried to switch off animations with NoopAnimationsModule and with passing [animations]="false" to the ngx-charts-pie-chart but both haven’t worked. Angular animation module is trying to get styles of the <svg> elements like <g>. And even switching off animations doesn’t stop animation module from call cloakAndComputeStyles towards <g> elements which are undefined in SSR. Still trying to find the workaround. I’ll post an answer here if we will find it earlier then Angular team will fix it.
