Question

having a weird issue that I haven t seen anything similar to before I m trying to run a `BigQueryLoadGoogleCloudStorage` task which I wrote but that isn t really helping grimacing and passing in `schema` as a list by the time `schema` is used in `run` somehow the order of the list is being altered causing the columns to be mis identified any idea what might be messing with the `schema` input to my task some kind of argument validation or copy maybe context <https github com PrefectHQ prefect blob master src prefect tasks google bigquery py L346 L409>

Hey Brett I think it might be the same issue as <https prefect community slack com archives CL09KU1K7 p1574761775447400 thread ts=1574761775 447400>

Try wrapping the schema in a `Constant schema ` to force the order to be preserved

We need to improve introspection of lists of constants I think

yep that fixed it I can see now why it works the way it does but it can definitely be counterintuitive and you might not notice right away
