Subject: fix(runtime-core): always set invalid vnode type (#820)
X-Git-Tag: v3.0.0-alpha.9~36
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=28a9beed1624de9812e0f4ce9b63f7f3ed2c6db8;p=thirdparty%2Fvuejs%2Fcore.git

fix(runtime-core): always set invalid vnode type (#820)

Currently, when a component used is not properly registered, we have a warning and the vnode type is set to a Comment type in DEV mode. But in prod mode, we have no default value, making such an application broken and throw a strange error (`can not read _isSuspense of undefined`).

This commit avoids such an error in prod mode (as it is currently the case in Vue 2.x).
