fieldMeta not set by async validator #2033
Description
Describe the bug
If fieldMeta doesn't exist when an async validator runs, it won't be created. (synchronous validators do cause the meta to get created).
If the meta already exists (because you have a form.Field for that field, or because you do something like setFieldValue('age', 2)), the error gets added to the fieldMeta without a problem.
Your minimal, reproducible example
https://stackblitz.com/edit/tanstack-form-vxfykhc5?file=src%2Findex.tsx,package.json
Steps to reproduce
- Submit the form without clicking anything else.
form.errorsshows errors at the form level, but "Age Meta" remains empty - Change
onSubmitAsynctoonSubmit, then submit the form. The meta gets created as expected.
Expected behavior
If errors happen when doing an async validation, the field meta should be created if necessary.

fix: async validation for unmounted fields
literalpie commentedon Mar 2, 2026
This issue is a pretty big priority for us because of the way a few things interact:
useFormContextto get/set value and state on fields that do not have aform.AppFieldmounted. I have found that, besides this issues, fieldMeta is the most reliable way to get the error state of fields.So I made a PR with a proposed fix for this.
