Fruit Name was not set on request.

Error message

Fruit Name was not set on request.

What it means

WebApplicationException (422) from FruitResource.update: the PUT request body's Fruit object has a null name, which the endpoint's manual validation rejects. The input at fault is the 'name' field of the deserialized Fruit request body; bean validation on @NotNull Fruit alone did not cover it, so the guard fires.

Solutions

1. Send the complete entity including name in the PUT body.
2. Validate on the client that name is non-null before the request.
3. Change the endpoint to PATCH semantics if partial updates are intended.

Example fix

// before
{"id": 1}
// after
{"id": 1, "name": "Banana"}

if (fruit == null || fruit.getName() == null || fruit.getName().isBlank()) {
    throw new IllegalArgumentException("PUT body must include a non-blank name");
}

boolean hasName(io.quarkus.it.hibernate.multitenancy.fruit.Fruit f) {
    return f != null && f.getName() != null && !f.getName().isBlank();
}

try {
    return target("/fruits/" + id).request().put(Entity.json(fruit), Fruit.class);
} catch (WebApplicationException e) {
    if (e.getResponse().getStatus() == 422) { /* fill name and retry once */ }
    throw e;
}

When it happens

Trigger: PUT /fruits/{id} with JSON body missing "name" or with "name": null.

Common situations: Partial updates sent to a full-replace PUT endpoint, unpopulated client DTO, or serialization dropping null/blank fields.
