Transforming constants with lodash breaks the translations

[manuganji]

// constants.js

export const OFFER_TYPES = {
  RENT: {
    code: "rent",
    label: t`Rent`,
  },
  SALE: {
    code: "sale",
    label: defineMessage({ id: `Sale`, message: t`Sale` }), // t`Sale`,
  },
};

// This works.
export const codeToOfferTypeLabel = Object.fromEntries(
   Object.values(OFFER_TYPES).map((type) => [type.code, type.label])
);


// This doesn't work.
export const codeToOfferTypeLabel = _.fromPairs(
  _.values(OFFER_TYPES).map((type) => [type.code, type.label])
);

I later access {i18n._(codeToOfferTypeLabel[listing.offerType])} within React. Only one of the variants works. I believe this has something to do with lodash's internal DS or with the way modules are exported.

They both work in DEV but only the Object variant works to produce build. I'm using "next.js"

To use translations on constants files you must use defineMessage, feel free to check documentation.
I'm off for holidays, I'll take Lingui control in a few days.

Thank you so much for replying on a holiday, @semoal. My build is again not working. I'll try your suggestion out.
