Fix cart price null crash

[Abhishekvenky010]

Fixes a runtime crash in POST /store/carts/{id}/line-items when a variant exists but has no calculated price for the cart’s region/currency. The code previously accessed calculatedPriceSet without checking for existence, causing a TypeError and resulting in a 500 error instead of a proper validation error.

This change adds a guard for calculatedPriceSet and ensures the flow returns the intended INVALID_DATA error for missing variant prices.

Thanks for the contribution! A few items need to be addressed before this can move forward:

The one-line code fix is sound and minimal: guarding calculatedPriceSet before reading calculated_amount prevents the TypeError, and the pre-existing priceNotFound check still surfaces the intended INVALID_DATA error. Two things need fixing before approval: the changeset content is incorrect, and the PR template's Testing section is not filled in. A regression test would also strengthen this core-flow change.

• .changeset/fix-calculatedPriceSet-guard.md is wrong: it targets @medusajs/query with unrelated text ('Refactor query logic...'). It should target @medusajs/core-flows (patch) and describe this cart pr
• Fill in the PR template's Testing section describing how the no-regional-price case was verified (adding a line item now returns INVALID_DATA instead of a 500).
• Consider adding a regression test covering the variant-without-price path in get-variants-and-items-with-prices.

Thanks for the contribution! We need more information before reviewing this further.

Good progress since the prior review: the changeset now correctly targets @medusajs/core-flows and a regression test was added for the variant-without-price path. The one-line guard is sound and lets the flow surface the intended INVALID_DATA error instead of a 500. One item from the prior review is still open: the PR description does not follow the template and the Testing section is not filled in.
