Invalid regular expression: invalid group specifier name

[ant-dep-linxea]

Versions

• @prismicio/client: 7.21.1
• node: 24.12

Reproduction

As reproduction, you can use iOS 16.0 with safari (also the case for 18.7, 15.8 and some others)

Additional Details

When upgrading @prismicio/client from 7.21.0 to 7.21.1 (and further) some of our iOS / Mac OS users got an app crash and we have data dog reports of Invalid regular expression: invalid group specifier name.

Steps to reproduce

What is expected?

What is actually happening?

We could not reproduced in local env for now and any case we would have only the node module errors

Hi @ant-dep-linxea, thank you for the report.

Could you try this prerelease version and let us know if it fixes the issue? You can find the details for the fix here: #436.

npm install @prismicio/client@pr-436

If you are unable to reproduce the issue yourself, we are likely to merge this fix anyway since it improves compatibility with older versions of Safari. You should see a reduction in Datadog errors after upgrading.

Related: #425, which fixes this issue in production builds. It's possible this package's code doesn't detect a production build in your environment.

Indeed it works thanks!
