Hello @flarco, I’m getting the following error. I checked the CSV file and noticed some data quality issues, but I can’t pinpoint exactly which ones Sling is flagging. Does Sling provide a way to see which rows are failing?

hey @Nishorgo yes, can you run with env var

SLING_KEEP_TEMP

? the temp file will not be deleted once the error occurs, so you'll be able to go to the row BQ is complaining about. Let me know if you think it's a bug.

No it's not a bug, I was asking for it as there are too many rows making it hard to pinpoint which rows were the source of the problem. Later, I checked BQ log to find the problem. My mistake was I thought the

CSV processing error

was coming from sling whereas it was coming from BQ. Thanks anyway.
