Babel babel -> Reflect meta

[hookercookerman]

Problem

• One is trying to package using a babel single deployable js/small size all that jazz.
• I am experiencing a problem via Reflect.metadata, whilst I am using all the known hacks for this, we are still seeing errors.

Area

Update Expressions -> ObjectMapper -> toDb

It is beyond a challenge to single down where this is going wrong. But in a nut shell undefined its getting parsed around for this mapper. I assume the metadata is not being handled correctly in the babel-plugin-transform-typescript-metadata and some meta data is not being picked up,

So this is more of a question; have you ever come across this issue ? as its kind of epic, hoping you might have some insights into this. Thanks

.babelrc config just in case

{
    "plugins": [
                ["babel-plugin-transform-typescript-metadata"],
        ["@babel/plugin-proposal-decorators", { "legacy": true }],
        ["@babel/plugin-proposal-class-properties", { "loose": true }]
    ],
    "presets": ["@parcel/babel-preset-env", "@babel/preset-typescript"]
}
