Regression in Function App Output
performanceActiveStableRecent updates have introduced regressions in the output handling of Function Apps, affecting reliability and user experience.
Score Breakdown
Heuristic ranking from public discussion signals — not a validated prediction of commercial opportunity, demand, or willingness to pay.
Composite 68/100 (High, unvalidated). Top driver: Willingness to pay (30% weight, 22.5 pts).
Heuristic only — often urgency map or random scaffolding on ingest, not measured mention frequency. Maps to XPS relevance (with market size).
LLM/mock judgment of intensity from title/summary text — not ops or ticket data. Maps to XPS quality (with willingness to pay).
LLM/mock purchase-intent guess from text — not invoices, surveys, or paid seats. Maps to XPS quality.
Heuristic/scaffold (often random or fixed on insert) — not a verified mention trajectory. Maps to XPS novelty.
Heuristic/scaffold (often random or fixed) — not TAM research. Maps to XPS relevance (with frequency).
Catalog notes (not predictive analysis)
Regression in Function App Output (performance). Catalog heuristic opportunity score: 68/100 — a chosen formula over discussion-signal facets, not evidence of demand, conversion, or willingness to pay. Treat as browsing rank, not a commercial prediction.

Source Examples
“az functionapp list --output table fails when appServicePlanId is absent ## Summary `az functionapp list --output table` fails when any Function App response omits `appServicePlanId`. JSON output succeeds. ## Reproduction ```bash az version # azure-cli 2.89.1 az functionapp list --output table ``` ## Actual result ```text ERROR: Table output unavailable. Use the --query option to specify an appropriate query. Use --debug for more info. ``` The debug traceback identifies the underlying failure: ```text File "azure/cli/command_modules/appservice/commands.py", line 35, in transform_web_output result["appServicePlan"] = result.pop("appServicePlanId").split("/")[-1] KeyError: 'appServicePlanId' ``` ## Expected result `az functionapp list --output table` should render the Function Apps list without failing when `appServicePlanId` is missing. The formatter should tolerate an omitted optional field. ## Workaround Explicitly project fields before requesting table output: ```bash az functionapp list --query '[].{Name:name,ResourceGroup:resourceGroup,Location:location,State:state}' --output table ``` ## Related issues - #33516: `az functionapp function keys list` broken in 2.87.0 - #16698: `az functionapp list` returns incorrect null values This may be another regression in the Function App output/transform layer introduced around 2.87.0.”
