Walkthrough

resolveText now returns null for resolver errors whose data starts with 0x77209fe8. It rethrows other errors. Tests cover both outcomes, and a patch changeset describes the update.

Changes

ENS resolver error handling

Layer / File(s) Summary
Handle resolver errors
packages/thirdweb/src/extensions/ens/resolve-text.ts, packages/thirdweb/src/extensions/ens/resolve-text-errors.test.ts, .changeset/ens-no-resolver-null.md
resolveText substitutes an empty result for matching resolver errors, which the existing result handling converts to null. Tests check this behavior and confirm other errors are rethrown unchanged. The changeset notes that resolveText and resolveAvatar return null for names without a resolver.

Priority: Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Suggested labels: packages, SDK

Merge Risk: Low · up to de02e

Lookups using different resolvers can briefly receive an incorrect null result, and the release version needs correction. Both issues are bounded but should be addressed before publishing.

Separate cached results by resolver.

If one resolver returns ResolverNotFound, this branch now caches null. A subsequent lookup for the same name and key on another chain or resolver can receive that cached null instead of its existing record for up to one minute. Include the effective chain and resolver address in the cache keys for both resolveText and resolveAvatar. (raw.githubusercontent.com)
