Description

The describe_schedule and batch_update_schedule functions produce a JSON parsing error when the payload contains an immediateModeScheduleActionStartSettings object. The ImmediateModeScheduleActionStartSettings rust type is defined as an empty struct which appears to have an erroneous JSON deserializer that will accept a StartObject token, but will not advance the token iterator through to the EndObject token.
https://github.com/awslabs/aws-sdk-rust/blob/main/sdk/medialive/src/model.rs#L34045
https://github.com/awslabs/aws-sdk-rust/blob/main/sdk/medialive/src/json_deser.rs#L11782-L11786

Example code:

let client = aws_sdk_medialive::Client::from_env();
let result = client
    .describe_schedule()
    .channel_id(&channel_id)
    .send()
    .await;

I expected an Ok result

Instead I got the following DescribeScheduleError:

ServiceError { err: DescribeScheduleError { kind: Unhandled(Error { reason: Custom("expected start object or null"), ...

With the following relevant trace logs:

Notice the part {\"immediateModeScheduleActionStartSettings\":{\"time\":\"2021-08-29T21:54:42.651\"}}, which is the object that breaks the deserializer.

This has been fixed in v0.0.17-alpha.
