quarkus.funqy.export does not match a function: ${export}

Error message

quarkus.funqy.export does not match a function: ${export}

What it means

Funqy Amazon Lambda must know which registered function to bind to the Lambda handler. When quarkus.funqy.export is set at runtime, the registry looks up a matching invoker; if the name matches no function, this RuntimeException is thrown.

Solutions

1. Set quarkus.funqy.export to the exact name of an existing @Funq function (usually the method name)
2. List functions in the app (grep for @Funq) and align the export value
3. Remove quarkus.funqy.export if there is only one function — it is auto-selected
4. Rebuild/redeploy after renaming functions so the registry matches config

Example fix

// before
quarkus.funqy.export=myFuntion
// after
quarkus.funqy.export=myFunction

String export = System.getenv("QUARKUS_FUNQY_EXPORT");
if (export != null && !registeredFunctionNames.contains(export)) {
    throw new IllegalStateException("quarkus.funqy.export '" + export + "' matches no function");
}

try {
    handler.handleRequest(input, output, context);
} catch (RuntimeException e) {
    if (e.getMessage().startsWith("quarkus.funqy.export")) log.error("Check QUARKUS_FUNQY_EXPORT value");
    throw e;
}

When it happens

Trigger: quarkus.funqy.export is set to a value that does not equal any registered Funqy function name (function names come from method names or @Funq naming).

Common situations: Typo in the export value; renaming a function method without updating quarkus.funqy.export; export set via env var in Lambda console pointing at a removed function; case mismatch.
