Incident report 10/02/2024

Impacted release: Deadpool/2.1.0

Time of detection: 10/02/2024, 3:50pm

Fix release: Deadpool/2.1.1

Reach: limited to flows picking JSON array in top level HTTP body

Impact: medium - workaround

Description

Three days after the Deadpool release, a regression bug has been identified on the capability to handle JSON payload containing an array of items at the top level of a HTTP body response.

Causes

• The issue was promptly analyzed after users reported this incident: the internal typing system wrongly identified the array and data picking.

Resolution

• Upon receiving the report and its analysis, a workaround was found: Using a Transform data step, user could use JSONPath to work with the JSON array and select to appropriate property.
• The impact was confined to workflows executed within the timeframe of the incident and utilizing data from JSON arrays at the root of a HTTP body response.
• The Mindflow engineering team has fixed the algorithm, solving the problem affecting some playbooks by restoring the proper processing of JSON arrays.

Follow-up

• The Mindflow development team will enrich the test suite around array processing to cover this use case.
• A new internal monitoring system for Mindflow DevSecOps team will detect failure rates to warn our support team ahead of any issue.
