hernanDatgDev opened a new issue, #5939:
URL: https://github.com/apache/camel-k/issues/5939
### What happened?
There's an issue providing an open-api spec (contract first) when the spec
has variables in the paths i.e.
```
rest().openApi("my-api.json")
```
my-api.json:
```
/users: ...
/users/{employeeid}: ...
/users/{employeeid}/location: ...
```
The api spec is provided via configmap and endpoints without variables can
be reached as expected. There is an index out of bounds error when trying to
reach endpoint `/users/{employeeid}` with `/users/myid123`:
```

(vert.x-eventloop-thread-0) Failed handling platform-http endpoint /. Caused

```
What I noticed is that endpoing `/users/{employeeid}/location` can be
reached with `/users/myid123/location` but the expectation is that there is a
header: `employeeid = myid123` however the value of the header is actually
`location`. It seems there is an offset when the endpoint is being parsed for
variables. The json I return shows the wrong value parsed for employeeId:
```
{
"employeeId": "location",
"location": "unknown"
}
```
In the HttpHelper.evalPlaceholders() that's throwing the exception, I
imagine there might be some misconfiguration on what is considered the "URL
path" vs the "consumerPath". I haven't been able to identify exactly where the
issue is but I imagine it will be in:
```
[1] at
org.apache.camel.component.rest.openapi.RestOpenApiProcessor.process(RestOpenApiProcessor.java:131)
```
📓 NOTE: When using the rest DSL e.g. `rest().get("/users/{employeeid}")`,
the api works as expected with no issues.
### Steps to reproduce
1. Create a basic open-api spec that includes variables in the path e.g.
`/users/{id}`
2. Create and provide this api spec (contract first) as a configmap in your
integration e.g.
```
// camel-k: resource=configmap:user-api-spec
...
configure() {
rest().openApi("open-api-spec.yaml");
...
}
```
3. Attempt to reach your endpoint that contains a variable in the path e.g.
`/users/id123`
