Ok please be sure to open an issue first before making any code changes. I’m not entirely sure what this is from limited gbq knowledge but tests are required as well Do we have a minimum version for pandas-gbq? Looks like this was added in 0.5. #21628 Looks like the relevant changes have been made in this PR. I think we are good to close this one. @WillAyd @TomAugspurger  Still need an issue to be opened for this along with the relevant test case(s) Wait I meant the changes this PR addresses, have already been made on master see #21628. So this is a duplicate. Hence we can close this? @WillAyd  @alimcmaster1 ah thanks for the link. Looks like it - closing as duplicative
