Description

The following works with Camel versions 3.11.3 and 3.13.0 but fails with version 3.11.4:

rest("/Assertion?authTokenSourceUri={" + HEADER_AUTH_TOKEN_SOURCE_URI + "}").id(ROUTE_REST_GET_ASSERTION)
    .get()
    .produces(MediaType.TEXT_XML_VALUE)
    .route()
    // route definition omitted

With version 3.11.4 this yields an org.apache.camel.ResolveEndpointFailedException:

Caused by: org.apache.camel.ResolveEndpointFailedException: Failed to resolve endpoint: servlet:///Assertion?httpMethodRestrict=GET due to: There are 1 parameters that couldn't be set on the endpoint. Check the uri if the parameters are spelt correctly and that they are properties of the endpoint. Unknown parameters=[{authTokenSourceUri={authTokenSourceUri}?consumerComponentName=servlet}]

Specifying the query parameter via DSL works with all three versions:

rest("/Assertion").id(ROUTE_REST_GET_ASSERTION)
    .get()
    .param()
        .name(HEADER_AUTH_TOKEN_SOURCE_URI)
        .type(RestParamType.query)
    .endParam()
    // rest is same as above
