UnmarshalTypeError - Error running in lambda #1

Open JonLittleIT opened 4 years ago

JonLittleIT commented 4 years ago

hey can you help me look at this issue in the code?

{ "errorMessage": "json: cannot unmarshal array into Go struct field CloudWatchEvent.detail-type of type string", "errorType": "UnmarshalTypeError" }

which is related to this func

func handler(event events.CloudWatchEvent) error { var finding GuardDutyFinding err := json.Unmarshal(event.Detail, &finding) if err != nil { log.Fatalf("Cannot unmarshal finding: %v", err) }

type GuardDutyFinding struct { ID string json:"id" Title string json:"title" Description string json:"description" Severity float32 json:"severity" Type string json:"type" AccountId string json:"accountId" }

any idea why I cant get this to run in Lambda?

Did you run the terraform to create the aws_cloudwatch_event_rule of type GuardDuty? Can you view it from the console?

JonLittleIT commented 4 years ago

I wanted to test just the lambda and I manually created the cloud watch rule which is set to trigger lambda on Guard Duty findings in Cloudwatch.

Without the filter for GuardDuty finding events you'll get CloudWatch events that the Lambda cannot process. It was only intended to process those of type GuardDuty.
