It seems AWS now generates a new parameter in task definition JSON automatically.
The new parameter in task definition:
"enableFaultInjection": false,
Error in the pipeline:
✖ ECS task definition parameter validation error:
Parameter validation failed:
Unknown parameter in input: "enableFaultInjection", must be one of: family, taskRoleArn, executionRoleArn, networkMode, containerDefinitions, volumes, placementConstraints, requiresCompatibilities, cpu, memory, tags, pidMode, ipcMode, proxyConfiguration, inferenceAccelerators, ephemeralStorage, runtimePlatform
