parser failed on Snowpark feature lineage json with cyclic dependency error

Not specified by the original author.

TL;DR

Traverse the lineage graph with a visited set so each node is processed once and cycles are reported instead of followed forever, because lineage graphs legitimately contain cycles through shared feature views and a naive recursive walk never terminates on them. Start with the Snowpark lineage JSON graph and the traversal code the agent ran on it, work on one affected call, record, or run first, and prove the fix there before running the full set. Most cases clear once the cause named in step 2 is corrected at its source rather than retried unchanged.

parser failed on Snowpark feature lineage json with cyclic dependency error

Use this when

• You see this exact message or symptom: parser failed on Snowpark feature lineage json with cyclic dependency error
• One run, record, call, or object is affected and you can name it
• A retry without changing anything reproduces the same result

Not for this skill when

• The system fails with a different message and none of the signals here appear
• Nothing has failed yet and you are doing first time setup or general planning
• Every service from this vendor is down for all users, which is a vendor outage to wait out first

Steps

1. Reproduce the failure once using the Snowpark lineage JSON graph and the traversal code the agent ran on it, and record the time, the workspace or account, and the one item it names. Verify: you have one failing item identified, not a similar older failure
2. Inspect the node where traversal re-enters a seen node, the graph size, and whether the parser used recursion without a depth or visited guard. Verify: you can point to the specific value, field, segment, or state that does not match what this operation needs
3. Apply the fix at that source: Traverse the lineage graph with a visited set so each node is processed once and cycles are reported instead of followed forever, because lineage graphs legitimately contain cycles through shared feature views and a naive recursive walk never terminates on them. Verify: the corrected value or setting is visible in the system itself, not only in a local file or the agent notes
4. Re-run the original operation on the single affected item first. Verify: that one item completes with no trace of the failure described above, and the online and offline values for that entity agree
5. Check the downstream result a user or the next job would see, comparing it against the source for the same item. Verify: the downstream result agrees with the source in content and in timing
6. Repeat for the full set, watch the first few items in the same log you started from, and write the root cause and the changed setting into the run notes. Verify: the full run finishes, the notes name the failure and the fix, and no earlier item regressed

Variant phrasings

parser failed on Snowpark feature lineage json with cyclic dependency error

The subject-first phrasing of the same failure. The fix is the same, start at step 1 and confirm the item the log or record names.

Tool-first phrasing of this failure

The phrasing searchers use once they know which system raised it. It is the same underlying problem, not a separate bug.

Why does this keep happening after a retry

The repeat-occurrence phrasing. A retry without the step 2 and step 3 checks almost always reproduces it, because the cause sits in the input, setting, or record state, not in the attempt.

Compatibility: Snowpark feature lineage exports, agent graph tooling.

Why it happens

Lineage is a graph, not a tree. Any walk that assumes a tree works on the training examples and breaks on the first real catalog with shared upstream views.
