Warning message in console when using the field validation for a string field.

[nipothar]

Bug report

What is the current behavior?

I have a field of type string, and when I add any validate method this is the warning message that shows up in console:

Warning: Cannot update during an existing state transition (such as within render). Render methods should be a pure function of props and state.

This occurs in the ForwardRef(Field). Full stacktrace shown below.

What is the expected behavior?

No console warning.

Sandbox Link

Not able to reproduce this.

What's your environment?

final-form: 4.20.7, Typescript, React application.

Bumping this issue, can someone help take a look at this? We are unable to have field validation for string type fields.

@nipothar Did you perhaps use State Hooks or redux inside one of your child components or validator?
