• I have searched for existing issues that already report this problem, without success.

Ionic Framework Version

v8.x

Current Behavior

Following from #28625

My only HTML file is: app.component.html

<ion-label>Home</ion-label>

provideServerRendering() causes

ERROR RuntimeError: NG0500: During hydration Angular expected a text node but found a comment node.

Fully:

RuntimeError: NG0500: During hydration Angular expected a text node but found a comment node.

Angular expected this DOM:

  #text(Home)  <-- AT THIS LOCATION
  …


Actual DOM is:

<ion-label _ngcontent-ng-c982784965="">
  <!--  -->  <-- AT THIS LOCATION
  …
</ion-label>

Note: attributes are only displayed to better represent the DOM but have no effect on hydration mismatches.

To fix this problem:
  * check the "_AppComponent" component for hydration-related issues
  * check to see if your template has valid HTML structure
  * or skip hydration by adding the `ngSkipHydration` attribute to its host node in a template
