--continue=false is ignored when used with apigeecli flowhooks attach

[lukebrody]

continueOnError is only added to the JSON if the value is true

apigeecli/internal/client/flowhooks/flowhooks.go

Line 39 in 47caa16

if continueOnErr {

But the default value of continueOnError is also true https://cloud.google.com/apigee/docs/reference/apis/apigee/rest/v1/organizations.environments.flowhooks#FlowHook

So, when --continue=false is passed, continueOnError is not included in the JSON, and is set to true.
