Claus Ibsen created CAMEL-25336:
-----------------------------------
Summary: camel-yaml-dsl-validator - report ${...} in a constant,
which is used as written and never evaluated
Key: CAMEL-25336
URL: https://issues.apache.org/jira/browse/CAMEL-25336
Project: Camel
Issue Type: Improvement
Components: camel-yaml-dsl
Reporter: Claus Ibsen
Fix For: 4.23.0
A constant is used as written, so a simple function inside it is not evaluated:
{code:yaml}
- setBody:
expression:
constant: '{"error": "unknown sku ${header.sku}"}'
{code}
answers the literal text {{unknown sku $\{header.sku\}}}. The route runs and
nothing reports it. In the local-model benchmark this was written 20 times
across the contracts-openapi-server, contracts-openapi-client and
connect-stock-api rungs ({{$\{header.sku\}}},
{{$\{exchangeProperty.orderId\}}}, {{$\{body[qty]\}}}).
Proposal: the YAML validator reports a simple function in a constant and shows
the simple form:
{noformat}Line 10: constant: ${header.sku} is not evaluated, a constant is used
as written: use simple: {expression: "{'error': 'unknown sku ${header.sku}'}"}
for a value with expressions{noformat}
Not reported: a constant set to a template header (CamelVelocityTemplate,
CamelThymeleafTemplate, ...), whose $\{...\} the template engine evaluates;
{{$\{HOME\}}}-style text; property placeholders; resource: constants.
