[BUG] Relaunch workflow converts large numbers in array of structs to objects.

[njubatyrov]

Describe the bug

When relaunching a workflow in FlyteConsole, large numbers within an array of structs are incorrectly converted into objects. For example, 1716759253199713 will become { "low": 695446369, "high": 399714, "unsigned": false }. This issue specifically occurs when the value of a key within the struct of an array is a large number, such as a Unix timestamp in microseconds.

The root cause appears to be in the parseJson.ts of flyteconsole repo. This file parses JSON and returns a Long type for large numbers. However, when this Long type is included when pressing "Relaunch" button, it is not correctly serialised and thus potentially causing unexpected behaviour.

Expected behavior

When relaunching a workflow, the input data should be accurately populated in the text area prior to launch.

Additional context to reproduce

1. Create a workflow where the input arguments are a collection of objects, and one of the key/value pairs is an integer that overflows JavaScript's Number type.
2. Once the job is complete, click "Relaunch". You will observe that the value has been converted into an object.

The issue you described seems to be related to how FlyteConsole handles large numbers during JSON parsing and serialization. Specifically, the Long type used for large numbers is not correctly serialized when relaunching workflows, leading to unexpected behavior.

cc: @jsonporter , can you take a look? This seems to be particular to the browser javascript, but maybe we can catch this error earlier?

@eapolinario / @jsonporter this is actually a struct and a json type. @njubatyrov If you use Flyte native float or int it does work right as seen below.

The problem is possibly with json schemas in the return

@kumare3

The issue only happens when you have an input as an array of dataclass objects which is converted to struct.

@njubatyrov we are working on an complete JSON overhaul in flyte - follow the issue - #5318
