First verify you are fetching the information correctly. Use console log and go to network tab and verify you are fetching the data correct, you might have to comment out vue-head. But what I think is that the problem might be due to vue-head rendering before the api call finishes then no data is being passed.
If you are using vue-router this can be easily solved with beforeRouteEnter() hook. But if not! apparently vue-head has an event that you can emit to update the component after render.
I haven’t tried this but it should work. you can add the function below to your methods and call it after the promise is resolved i.e in the then closure.
methods: {
getProgram() {
this.api.http.get(`videos/program/${this.programSlug}`)
.then(response => {
this.programs = response.data
this.$emit('updateHead')
})
.catch(error => {
this.errors = error
});
}
}
