I'm having this exception calling @query in mongoDB reactive in webflux springboot 3.3.4 when a table result of first query is empty calling other repository to search in other table that have the record searched.

return productRepository
    .findBySearchKey(code, channel, touchpoint)
    .doOnNext(AEMProductData -> log.debug("{} product on Products in MongoDB: {}", logHash, AEMProductData.toString()))
    .map(aemProductEntity -> {
    DozerBeanMapper mapper = new DozerBeanMapper();
    BaseProductsResponse response = mapper.map(aemProductEntity, AEMProductResponse.class);
    
                            return response;
                })
                .switchIfEmpty(aemProductRepository
                                .findBySearchKey(code, channel, touchpoint)
                                .doOnNext(aemProductEntity -> log.debug("{} product on AEMProducts on MongoDB: {}", logHash, aemProductEntity.toString()))
                                .map(aemProductEntity -> {
                                    DozerBeanMapper mapper = new DozerBeanMapper();
                                    BaseProductsResponse response = mapper.map(aemProductEntity, AEMProductResponse.class);
                                    
                                    return response;
                                })
                );

In the switchEmpty generate exception in jdk.internal.reflect in method public Object invoke(Object obj, Object[] args) throws InvocationTargetException { we are using JDK21.0.6:

.switchIfEmpty(aemProductRepository
                                .findBySearchKey(code, channel, touchpoint)
                                .doOnNext(aemProductEntity -> log.debug("{} product on AEMProducts on MongoDB: {}", logHash, aemProductEntity.toString()))
                                .map(aemProductEntity -> {
                                    DozerBeanMapper mapper = new DozerBeanMapper();
                                    BaseProductsResponse response = mapper.map(aemProductEntity, AEMProductResponse.class);

Somebody can tell us what happening? We are using lombok hibernate and Mongo Reactive Repository and Springboot 3.3.4 with Webflux.
