App is crashing when heading tags are used

• [X] My issue does not look like “The HTML attribute 'xxx' is ignored” (unless we claim support for it)
• [X] My issue does not look like “The HTML element <yyy> is not rendered”

Other HTML tags (like p, a, etc) are working fine.

Looks like a mismatch in domutils version; make sure the version range required by @native-html/transient-render-engine (^2.8.0) matches the resolved version in your project.

EDIT: erratum

Looks like a mismatch in domutils version; make sure the version range required by @native-html/transient-render-tree (^2.8.0) matches the resolved version in your project.

Since @native-html/transient-render-tree is deprecated , "@native-html/transient-render-engine" "11.2.3" is auto-resolved.

@gs-alranjan You're correct, I meant @native-html/transient-render-engine.

[gs-alranjan]

@jsamr still, headings are causing issues to be rendered. Any alternate solution?

This still holds true. Depending on your package manager, you can see which version(s) of a peculiar package are installed. yarn why domutils or npm why domutils. Happy to reopen if this really turns out to be a bug, but currently it does seem like a packager issue.
