Dear MendelianRandomization authors, I seem to be getting this error. Might you happen to know the cause? Thanks. Esther

All your bx are all exactly the same! This is a little suspicious, and it stops the method from working. I highly suspect some (if not all) of your genetic variants are perfectly correlated, whereas the methods typically require variants to be uncorrelated.
