Common errors with crystall.io lines

  • RESELLER but publisher 841 lines

    If the account is yours, declare it DIRECT. If a partner holds it, ask crystall.io why the account is listed as PUBLISHER.

  • Seller ID not found 90 lines

    Ask crystall.io for the account ID it lists for you in its sellers.json, correct the line, or remove it if you no longer work with them. Buyers that check sellers.json drop these paths.

  • Seller type BOTH 8 lines

    The account is listed as BOTH, so sellers.json alone cannot tell a buyer which relationship applies. Nothing to fix on your side; buyers usually look at the seller's domain.
