checkEntityAndSyncPath and the groups module

The function checkEntityAndSyncPath uses key() to get the entity type by the first route parameter. This works in most cases but not when used on group content cause this entity requires 2 parameters group id and group content id (ex: group/1/group_content/3). So when the you programmatically create group content the fieldable path field on the group entity gets updated with the path of the group content.

So I would suggest using the last route parameter to sync the path, this will work in all cases.
