[GitHub] [camel-k] barmyard opened a new issue #2139: Wiretap to Kamelet does not work in YAML
barmyard opened a new issue #2139:
URL: https://github.com/apache/camel-k/issues/2139
I am observing errors while writing a YAML integration containing a wiretap to a Kamelet, here is a minimal example: This example should log "Hello from Camel K yaml" twice.
```yaml
- from:
uri: "timer:yaml"
parameters:
period: "1000"
steps:
- set-body:
constant: "Hello Camel K from yaml"
- wiretap:
uri: "kamelet:logger?message=${body}"
- to: "log:info"
```
Where the logger Kamelet is just a simple sink Kamelet that logs:
```yaml
apiVersion: camel.apache.org/v1alpha1
kind: Kamelet
metadata:
name: logger
namespace: default
labels:
camel.apache.org/kamelet.type: "sink"
spec:
definition:
title: "Logger"
description: Logger
required:
- message
properties:
message:
title: Message
description: Message
type: string
flow:
from:
uri: "kamelet:source"
steps:
- log: "{{message}}"
```
After `kubectl apply -f ` and `kamel run`, I receive the following error:
`WARN [org.apa.cam.pro.WireTapProcessor] (Camel (camel-1) thread #3 - WireTap) Error occurred during processing Exchange[72E859E2207EED5-0000000000000005] wiretap to kamelet:logger?message=${body}. This exception will be ignored.: org.apache.camel.NoSuchEndpointException: No endpoint could be found for: kamelet://logger?message=Hello+Camel+K+from+yaml, please check your classpath contains the needed Camel component jar.`
Changing the `wiretap` to a `to` statement works: ("Hello .. " is printed once every second)
```yaml
- from:
uri: "timer:yaml"
parameters:
period: "1000"
steps:
- set-body:
constant: "Hello Camel K from yaml"
- to:
uri: "kamelet:logger?message=${body}"
```
Changing the `kamelet:logger` to the baked in `log` also works: ("Hello .. " is printed twice every second)
```yaml
- from:
uri: "timer:yaml"
parameters:
period: "1000"
steps:
- set-body:
constant: "Hello Camel K from yaml"
- wiretap:
uri: "log:info"
- to: "log:info"
```
Another interesing thing: when I remove the final `to: log:info` statement, it doesn't work either:
```yaml
- from:
uri: "timer:yaml"
parameters:
period: "1000"
steps:
- set-body:
constant: "Hello Camel K from yaml"
- wiretap:
uri: "log:info"
```
I am not sure if miss something, or it's a bug. After a discussion on Zulip chat with @lburgazzoli, he mentions there might be an issue with load templates. Similar problems arise with components like `enhance`, and I suspect it might be the same issue.
Mind you: I don't have a lot of Camel (K) experience, so I hope I formulated everything well.

I've checked this problem and it was caused by the usage of `wiretap` which should be instead `wire-tap` in yaml language. If you try
```
- wire-tap:
uri: "log:wiretap"
```
you should have it fixed. Please, reopen if you face any other problem.
