Google Assistant Virtual Output problem

[maxwelllai]

Everything seems in normal working condition, But when I check my Google cloud console in the API request monitor section, it shows the message below with red color highlight.

Also, when I say" Give me a direction to xxx"
and It respond just like what it suppose to(Voice respond with virtual text output “Ok, getting you direction to xxxx”), but then I was expecting there should be some sort of Map pop out beside the text, IT DID NOT. It shows only text, Other than this, everything looks normal, video output etc.
Any idea what’s the problem?
