Failed to transform Message when switch header-enricher from 1.3 to 2.x in Spring Cloud Dataflow

Getting Oracle 11.2 Unsupported Error when using Spring Cloud Data Flow 2.0.1When setting spring cloud data flow (scdf) 2.x as maven dependency of a regular spring boot app, the dataflow local server is not starting

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

I create the Spring Cloud Data Flow stream with header-enricher 1.3 and deploy it, it works fine. But when I switch to header-enricher 2.x in same SCDF environment, it throw "Failed to transform Message exception".

I'm wondering what's the difference between 1.3 and 2.x that cause the issue?

Here is 1.3 stream definition:

app register --name header-enricher_1_3 --type processor --uri http://repo.spring.io/release/org/springframework/cloud/stream/app/header-enricher-processor-rabbit/1.3.1.RELEASE/header-enricher-processor-rabbit-1.3.1.RELEASE.jar 



stream create Header_TEST --definition "trigger --time-unit=MINUTES --initialDelay=0  --fixed-delay=500  --payload={'testWords':'Hello World!'} | header-enricher_1_3  --headers='testWords_header=payload.testWords' --outputType=application/json  | log --expression=headers.testWords_header" --deploy

It works fine, we can get " Hello World!" in log:

I got an exception says:

In Environment Variables, we also tried several configurations, but none of them is working:

  spring.cloud.stream.bindings.output.destination=Header_TEST.trigger

  spring.cloud.stream.rabbit.bindings.output.producer.routing-key-expression=headers.type

I'm wondering what's the difference between 1.3 and 2.x that cause the issue?

Here is 1.3 stream definition:

app register --name header-enricher_1_3 --type processor --uri http://repo.spring.io/release/org/springframework/cloud/stream/app/header-enricher-processor-rabbit/1.3.1.RELEASE/header-enricher-processor-rabbit-1.3.1.RELEASE.jar 



stream create Header_TEST --definition "trigger --time-unit=MINUTES --initialDelay=0  --fixed-delay=500  --payload={'testWords':'Hello World!'} | header-enricher_1_3  --headers='testWords_header=payload.testWords' --outputType=application/json  | log --expression=headers.testWords_header" --deploy

It works fine, we can get " Hello World!" in log:

Here is the 2.x Stream definition:

I got an exception says:

I'm wondering what's the difference between 1.3 and 2.x that cause the issue?

Here is 1.3 stream definition:

app register --name header-enricher_1_3 --type processor --uri http://repo.spring.io/release/org/springframework/cloud/stream/app/header-enricher-processor-rabbit/1.3.1.RELEASE/header-enricher-processor-rabbit-1.3.1.RELEASE.jar 



stream create Header_TEST --definition "trigger --time-unit=MINUTES --initialDelay=0  --fixed-delay=500  --payload={'testWords':'Hello World!'} | header-enricher_1_3  --headers='testWords_header=payload.testWords' --outputType=application/json  | log --expression=headers.testWords_header" --deploy

It works fine, we can get " Hello World!" in log:

In Environment Variables, we also tried several configurations, but none of them is working:

  spring.cloud.stream.bindings.output.destination=Header_TEST.trigger

  spring.cloud.stream.rabbit.bindings.output.producer.routing-key-expression=headers.type

I'm wondering what's the difference between 1.3 and 2.x that cause the issue?

Here is 1.3 stream definition:

app register --name header-enricher_1_3 --type processor --uri http://repo.spring.io/release/org/springframework/cloud/stream/app/header-enricher-processor-rabbit/1.3.1.RELEASE/header-enricher-processor-rabbit-1.3.1.RELEASE.jar

It works fine, we can get " Hello World!" in log:

In Environment Variables, we also tried several configurations, but none of them is working:

  spring.cloud.stream.bindings.output.destination=Header_TEST.trigger

  spring.cloud.stream.rabbit.bindings.output.producer.routing-key-expression=headers.type

The issue is opened in GitHub also: https://github.com/spring-cloud-stream-app-starters/header-enricher/issues/23
