Croway opened a new pull request, #22404:
URL: https://github.com/apache/camel/pull/22404
## Summary
- Fix `YamlRoutesBuilderLoader.extractCamelEndpointUri()` where Pipe YAML
Kamelet properties containing `{{placeholder}}` patterns get URL-encoded to
`%7B%7Bplaceholder%7D%7D` by `URISupport.createQueryString(params)`, preventing
property resolution at runtime.
- Wrap property placeholder values with `RAW(...)` before calling
`createQueryString` so that curly braces are preserved as-is in the query
string.
## Details
**JIRA:** [CAMEL-23284](https://issues.apache.org/jira/browse/CAMEL-23284)
When a Pipe YAML definition includes Kamelet properties with Camel property
placeholders (e.g., `{{timer.message}}`), the `extractCamelEndpointUri` method
builds a query string using `URISupport.createQueryString(params)`. This method
URL-encodes special characters, turning `{{` and `}}` into `%7B%7B` and
`%7D%7D` respectively. As a result, the Camel property placeholder resolver
cannot recognize or resolve these values.
The fix iterates over the `params` map entries before query string creation
and wraps any `String` value containing `{{` with `RAW(...)`. The `RAW()`
marker tells Camel's URI support to preserve the value as-is without
URL-encoding.
## Test plan
- [ ] Verify that Pipe YAML definitions with `{{placeholder}}` Kamelet
properties resolve correctly at runtime
- [ ] Verify that Kamelet properties without placeholders are unaffected
