Review Comment:
For the `supported` cases, if there are exceptions,
`pb_encode` without `pcall` would get response_body like following quoted
text, which can also fail the test case.
In this test case, we mainly focus on the `unsupported` cases and the
corresponding error `bad argument #2 to '?' (number/'#number' expected for
field 'values', got string)`
