Region with id not found when populating the pricing context

Error message

Region with id ${req.filterableFields.region_id} not found when populating the pricing context

What it means

Thrown by setPricingContext when the region_id supplied on the request (req.filterableFields.region_id) does not correspond to an existing region. The middleware fetches the region to build pricing context (currency, tax rates) and refuses to continue with an unknown region.

Solutions

1. List valid regions via GET /store/regions and use a current id
2. If regions were re-seeded, clear cached region ids in the storefront (localStorage/cookies)
3. Pass no region_id and rely on the store's default region instead

Example fix

// before
GET /store/products?region_id=reg_stale

// after
GET /store/products?region_id=reg_current

const { regions } = await sdk.store.region.list()
const regionId = regions.find(r => r.id === requestedId)?.id
if (!regionId) {
  requestedId = regions[0]?.id // or re-prompt
}
const products = await sdk.store.product.list({ region_id: regionId })

const isExistingRegionId = (id: string, regions: {id: string}[]): boolean =>
  regions.some(r => r.id === id)

try {
  await sdk.store.product.list({ region_id: id })
} catch (e) {
  if (e.type === 'invalid_data' && /not found when populating the pricing context/.test(e.message)) {
    // refresh cached regions and retry
  }
  throw e
}

When it happens

Trigger: GET /store/products?region_id=reg_does_not_exist (deleted region, id from another environment, or a typo). Any store request that populates filterableFields.region_id with a stale value.

Common situations: Frontend caching an old region id after regions were re-created; copying ids across environments; region soft-deleted while the storefront still references it.
