Hello Roderick,I don't think this is the case, we were not using time travel at all and did not have this issue, it suddenly started to occur after a few weeks while we did not make any changes.We recreated the whole datastream and it started working...

Correct, you will recreate everything like it was as if you did a brand new start, but at least we can continue for today and investigate more (or hopefully find the answer here for what is actually happening)

Hi All,For now it could be solved (at least for me) by recreating the data streams with the same settings as before, but it does not feel as a solution, as we still need to know what is causing this (Google?)

Same thing here, anybody?Preview in SQL workspace works, export to sheets also works, but select query fails...
