Hi,
We are seeing the following error lately related to event monitoring data flow:
Job Name: Login Upload flow - Overwrite
Job Type: File Upload
Error: Something went wrong while executing the digest node: field-count, 35, and header's column-count, 34, do not match [error category: USER](xxxxxxxxxxyy_rtsxxxxxxxxxxxx_001)
Can anyone help with this issue please?
Thanks,
Ram
Hi @Ramkrishna Shirali - This is a schema mismatch error — the Event Monitoring data file being uploaded has 35 fields, but the dataset schema (defined in the dataflow's digest node) only expects 34 columns. The counts are off by one.
What caused it: Salesforce periodically adds new fields to Event Monitoring log files as part of seasonal releases. When they add a field to the LoginEvent log, the uploaded file gains a column but the CRM Analytics dataflow schema doesn't automatically update to match — hence the field-count vs header-count mismatch.
How to fix it:
- Download a recent LoginEvent log file from Event Monitoring and open it. Identify which field is new (compare against the 34 columns your digest node expects — the extra one will stand out).
- Update the digest node schema in the Login Upload flow dataflow to include the new field. You can do this in the dataflow JSON directly or via the UI dataflow editor — add the missing column with the appropriate data type.
- Re-run the dataflow after saving the schema update.
