Hello,

I am currently facing issue to display http traces when there is no response in the trace (probably because the request is not completed).

Here is the error I can see in the browser:

TypeError: Cannot read property 'status' of undefined
at t.value (index.vue:150)
at o.chartData (traces-chart.vue:97)
at er.get (vue.runtime.esm.js:4444)
at er.evaluate (vue.runtime.esm.js:4549)
at o.chartData (vue.runtime.esm.js:4801)
at o. (vue.runtime.esm.js:503)
at er.get (vue.runtime.esm.js:4444)
at new er (vue.runtime.esm.js:4433)
at o.t.$watch (vue.runtime.esm.js:4911)
at pr (vue.runtime.esm.js:4871)

I checked https://github.com/codecentric/spring-boot-admin/blob/master/spring-boot-admin-server-ui/src/main/frontend/views/instances/httptrace/index.vue#L158 and apparently there is no null check on the response.

Version of Spring boot admin: 2.1.6
Version of Spring boot: 2.1.5.RELEASE

Thank you
