Hi @taylor, @edgar_ramirez_mondragon, I see that target-bigquery tries to manipulate (merge) state messages, which is its default behavior, but not desired for your data and use case and it's failing on your state file. Try disabling state merging. State message won't be manipulated in any way, but will just be passed as is. Whatever state message we get - that will be our state file. Method A. When you call target-bigquery thru command line, pass this flag:

'--no-merge_state_messages'

Method B. Disable state merging via target config file

{
  "project_id": "{your-project-id}",
  "dataset_id": "{your_dataset_id}",
  "merge_state_messages": 0
}
