The required value gets into the variable of the VUE component, but the v-if directive does not work, how to fix it?

Question

Vue.js

Good afternoon, ladies and gentlemen. Using the mounted hook, I send a request to the server, depending on the result, I put the value true or false in the active variable from the data object. I put a v-if directive on the block that listens to this variable.
As a result, even when the variable contains the value false (checked through the console), the v-if directive still does not work.
There is a feeling that the directive does not track the change in the state of the variable.
