Question 2: I have 7 queries on my first test experiment (the one where preview mode works - though it has not gathered any data in 35 days despite me being able to see hundreds of pageviews on that page in Google Analytics for that duration. A growthbook team member helped me sort out some errors with these queries the other day caused by my dataset not being defined by default in the assignment queries but now I have different errors: 2 of 5 show the “Could not cast literal “2023-12-21 231400" to type DATE at [98:22]” and everything else shows “_No rows returned”._ Btw I’m far from a developer so I feel i’m already over my head in GB but any way someone can help guide me would be appreciated. I am on a paid plan.

Happy to help with this one. Whatever query is failing probably has some kind of template variable, like
{{ startDate }}
You probably need need to wrap with something like
DATETIME('{{ startDate }}')
If you share the full query that is failing in that modal I can try to help you out.
Another issue why you might not be seeing any data on your other queries is that for some reason your experiment exposure IDs aren't matching with your metric IDs, but I'm not certain. Perhaps @brief-honey-45610 can help with that next week if that is indeed still a problem.

Thanks for your willingness to help! Here’s one of the full queries that display the error: -- AOV (revenue) WITH __rawExperiment AS ( SELECT user_pseudo_id as anonymous_id, TIMESTAMP_MICROS(event_timestamp) as timestamp, experiment_id_param.value.string_value AS experiment_id, variation_id_param.value.int_value AS variation_id, geo.country as country, traffic_source.source as source, traffic_source.medium as medium, device.category as device, device.web_info.browser as browser, device.operating_system as os FROM
