"No data" message in Google Data Studio chart after connecting dataset from BigQuery?

I am trying to connect and visualise aggregation of metrics from a wildcard table in BigQuery. This is the first time I am connecting a table from this particular Google Cloud project to Data Studio. Prior to this, I have successfully connected and visualised metrics from other BigQuery tables from other Google Cloud projects in Google Data Studio and never encountered this issue. Any ideas? Could this be something to do with project-level permissions for Google Data Studio to access a BigQuery table for the first time?

More details of this instance: the dataset itself seems to be successfully connected into Data Studio so errors were encountered. After adding some charts connected to that data source and aggregating metrics, no other Data Studio error messages were encounterd. Just the words "No data" displayed in the chart. Could this also be a formatting issue in the BigQuery table itself? The BigQuery table in question was created via pandas-gbq in a loop to split the original dataset into individual daily _YYYYMMDD tables. However, this has been done before and never presented a problem.

I have been struggling with the same problem for a while, and eventually I find out that, at least for my case, it is related to the date I add to the suffix (_YYYYMMDD). If I add "today" to the suffix, DataStudio won't recognize it and will display "no data", but if I change it to "yesterday" (a day earlier), it will then display the data correctly. I think it is probably related to the timezones, e.g., "today" here is not yet there in the US, so the system can't show. Hopefully it helps.
