I am having a problem with a data transfer from Google Ads. When I schedule the backfill I get the following error for some dates:

Invalid value: Load configuration must specify at least one source URI

When I check the log inside of the details of execution I get the following message:

Failed to start job for table p_ClickStats_5419416216$20201117 with error INVALID_ARGUMENT: Invalid value: Load configuration must specify at least one source URI

The weird part is that this happens for random dates which I had transfered before in a previous transfer. Did anyone have a problem similar to that?
