Uncaught TypeError: Cannot add property initialized, object is not extensible
j-perl opened this issue · comments
Hi,
We're currently using formiojs (4.12.1) and react-formio (4.3.0) and we're trying to update these dependencies to the latest stable versions (4.17.2 and 5.2.3 respectively at the time of this writing), however, when displaying a form, we're getting this error, which comes from this piece of code :
Apparently, modifications are made to the i18next object that is not extensible.
In strict mode, attempting to add new properties to a non-extensible object throws a TypeError.
Strangely enough, I couldn't find any thread mentioning this issue so I'm wondering whether we are not the only one having it. Do you have any idea what I could be doing wrong?
For those having the same problem, I've found that importing and passing our own instance of i18next through the options parameter makes the problem go away.
