Context of the Vue component is going wrong

Question

I have a problem in the development of a project using in Vue2, when I look for the context of the component, it does not return me the "right" context, as for example the:

$router

that if you want to appear in the context that comes, the object I receive when I search is the following:

{"a":{"staticRenderFns":[],"_compiled":true,"_scopeId":"data-v-4c198e4e","beforeCreate":[null,null],"__file":"src\\components\\Calendar.vue","beforeDestroy":[null],"_Ctor":{}}}

and so I’m not able to do the route manipulation without refreshing the system for example. NOTE: may be some update of the last half year, I worked with VUE in November and December, but January changed jobs and in the meantime I could not keep track of the performance of the framework unfortunately.

thanks in advance for the help.
