Id was invalidly set on request.

Error message

Id was invalidly set on request.

What it means

Same as errorIndex 3950 but in the datasource-variant FruitResource: POST rejects a body whose id is already set with HTTP 422 because identifiers must be generated by the persistence layer, not supplied by clients.

Solutions

1. Omit the id (or null it) in the POST body.
2. Use PUT /fruits/{id} for updates.
3. Configure the client serializer to skip the id on create.

Example fix

// before
{"id": 7, "name": "Cherry"}
// after
{"name": "Cherry"}

if (fruit.getId() != null) {
    fruit = new Fruit(fruit.getName()); // strip id before create
}

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

try (Response r = target("/fruits").request().post(Entity.json(fruit))) {
    if (r.getStatus() == 422) { /* id was set; retry without id */ }
}

When it happens

Trigger: POST a Fruit JSON body containing a non-null "id" field to the datasource-based /fruits endpoint.

Common situations: Reusing a fetched entity object for create, client DTO defaults id, or POST used instead of PUT for updates.
