Spring Boot 3 RC1 w/ R2DBC mapping error

[mycroft11]

Hello,

Calling the following:

dao().getRepository().query(query -> query
                      .select(
                                    entity1.currencyId,
                                    entity1.defaultCurrency,
                                    entity1.depositEnabled,
                                    entity1.withdrawEnabled,
                                    entity2.title
                      )
                      .from(entity1)
                      .innerJoin(entity2)
                      .on(entity1.currencyId.eq(entity2.currencyCode))
                      .where(entity1.memberId.eq(testId)))
.all()
.collectList()

Generates an exception:

I assume you're using 8.0.0-M2, does this work with 7.2.0?

[mycroft11]

Thank for the reply @lpandzic ! Yes, both 8.0.0.-M2 and 7.2.0 fail with spring boot 3 rc2 :(

I tried to figure out where the converter fails to register, but no luck. Can you help?

[lpandzic]

7.2.0 doesn't work with Spring Boot 3, does it work with 7.2.0 and Spring Boot 2?

I'm closing this down as stale. Feel free to reopen if you can provide more info or a reproduction.
