Cannot read property 'start' of null

[richardvaldiviesomacias]

We are using the version 1.2.2 and we tried to upgrade to the latest version. We got the following error: Cannot read property 'start' of null. Could you please help us?

<InputMask type="tel" className="" autoComplete="tel-national" placeholder="(555) 555-0199" mask="(999) 999-9999" value= onBlur= onChange=/>

Could you provide a demo repo with reproducible error?

I have this problem as well. Using Enzyme to simulate an onChange event causes this error to throw. I will try and get a demo repo up for you.

react-input-mask: 2.0.1
enzyme: 3.3.0

It must be due to firing onChange on Input without focus. Have an idea how to fix it, but it's better to see a demo first.

Could you also try to set a focus on input and check if error is gone?

I created a demo app that replicates this issue.

travis output fwiw: https://travis-ci.com/crstamps2/react-input-mask-enzyme/jobs/128874350

Fixed in 2.0.2

While that issue was resolved, upgrading the package caused a new issue.

It happens because of the undefined this.searchTerm. I suppose it must be this.phone_number.length instead.

You're right. My bad. All is good with this then! Thanks for the quick responses!

Fixed in 2.0.2

I'm using 2.0.4 and I get this error every time - even if I force a value into the field. There's just no explanation for it.

lo solucione quitando el onFocus del input que utilizaba
