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
