data pipeline failure error null values spike causing false anomaly alert

Not specified by the original author.

TL;DR

Fix this in the anomaly detector by acting on the exact message first: reproduce the failure on the smallest single item first, note the exact inputs that trigger it, and change only the input or setting the error names. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one item, then rerun the full scope and reconcile the counts.

data pipeline failure error null values spike causing false anomaly alert

Use this when

• The operation in the anomaly detector fails with this exact message: data pipeline failure error null values spike causing false anomaly alert.
• The same failure repeats on retry with unchanged inputs.
• A review, export or check is blocked until this item completes.

Not for this skill when

• The message is a permission or outage notice from the platform. Resolve that first, then return here if this error remains.
• The operation completes and you only disagree with its output. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in the anomaly detector, and copy the full message plus the item, user or metric involved into the run notes. Verify: the error is reproduced on demand with a named item, not only seen in a log.
2. Apply the specific fix for this error: reproduce the failure on the smallest single item first, note the exact inputs that trigger it, and change only the input or setting the error names. Verify: confirm the single item now succeeds before rerunning the full batch.
3. Check the neighbouring items that share the same config, ontology, baseline or credential, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Compare the result counts, decisions or alerts against the source in the anomaly detector so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
5. Rerun the original operation in the anomaly detector on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
6. Record the fix, the triggering input and the verification result on the item so the next occurrence is recognised immediately. Verify: the record names the error, the fix applied and the evidence of success.

Why it happens

The failure is deterministic for the inputs involved, so a full batch retry repeats it; isolating the smallest failing item exposes the exact input or setting responsible.

TL;DR

Fix this in the anomaly detector by acting on the exact message first: treat missing points as missing rather than zero in the detector input, and add a separate data absence alert with its own threshold so gaps page the pipeline owner instead. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one item, then rerun the full scope and reconcile the counts.

2. Apply the specific fix for this error: treat missing points as missing rather than zero in the detector input, and add a separate data absence alert with its own threshold so gaps page the pipeline owner instead. Verify: a simulated gap raises the absence alert and no fake drop alert fires.
3. Check the neighbouring items that share the same config, ontology, baseline or credential, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Rerun the original operation in the anomaly detector on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.

Why it happens

Filling gaps with zeros manufactures a drop to zero that the detector rightly flags; the bug is the fill, not the detection.

TL;DR

Fix this in Gainsight Data Designer by acting on the exact message first: add a null filter or a default value for the custom object field used in the Gainsight Data Designer aggregation, preview the fetch step to find the records carrying the null, fix or exclude those records at source, and rerun the aggregation job to completion. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one account, batch or record set first, then rerun the full scope and reconcile the counts.

Gainsight Data Designer aggregation job fails on null values in custom object

Use this when

• The operation in Gainsight Data Designer fails with this exact message or symptom: Gainsight Data Designer aggregation job fails on null values in custom object.
• The same failure repeats on retry with unchanged inputs.
• Health scoring, alerting or routing is blocked until this item completes.

Not for this skill when

• The message is an outage notice from the platform. Resolve that first, then return here if this error remains.
• The operation completes and you only disagree with its output quality. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in Gainsight Data Designer, and copy the full message plus the account, measure or job involved into the run notes. Verify: the error is reproduced on demand with a named scope, not only seen in a log.
2. Apply the specific fix for this error: add a null filter or a default value for the custom object field used in the Gainsight Data Designer aggregation, preview the fetch step to find the records carrying the null, fix or exclude those records at source, and rerun the aggregation job to completion. Verify: the smallest failing scope now completes, or the named account, measure or job behaves as the fix predicts.
3. Check the neighbouring accounts, measures or jobs that share the same config, schema or source, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Rerun the original operation in Gainsight Data Designer on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
5. Compare the result counts, scores or status against the source in Gainsight Data Designer so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
6. Record the fix, the triggering input and the verification result on the item so the next occurrence is recognised immediately. Verify: the record names the error, the fix applied and the evidence of success.

Why it happens

Aggregation jobs fail on null join or group keys in a custom object, because a single null key cannot be placed in any group and aborts the whole job.

Edge cases

• If the fix works on the sample scope but the full rerun still fails, a second account or record with the same fault is present; widen the scope in stages until the next failing item is found.
• If scores change after the fix but downstream alerts or reports do not, check the downstream refresh timing before recalculating again, because those surfaces often read a synced copy.
• If the source information itself is missing for the affected accounts, record that as a source gap rather than scoring the accounts as zero.
