Topic: Updating Data in react crashes MDBTable
**I have a table of multiple columns that represent a subscription, one of the columns is a Enum that is status of the subscription. I've added a filter that basically goes through a switch and filters data base on that.
For Some reason when I try filtering the data that i'm rendering to one one of the 3 statuses that are not active it crashes, I'm expecting to filter the data and rerender correctly.**
**The react app crashes with this error -->
react-dom.production.min.js:125 TypeError: Cannot convert undefined or null to object at Function.keys () at vendors.bundle.js:6 at Array.map () at t.value (vendors.bundle.js:6) at Ie (react-dom.production.min.js:104) at rh (react-dom.production.min.js:103) at zj (react-dom.production.min.js:228) at Th (react-dom.production.min.js:152) at tj (react-dom.production.min.js:152) at Te (react-dom.production.min.js:146) Me @ react-dom.production.min.js:125 react-dom.production.min.js:61 Uncaught TypeError: Cannot convert undefined or null to object at Function.keys () at vendors.bundle.js:6 at Array.map () at t.value (vendors.bundle.js:6) at Ie (react-dom.production.min.js:104) at rh (react-dom.production.min.js:103) at zj (react-dom.production.min.js:228) at Th (react-dom.production.min.js:152) at tj (react-dom.production.min.js:152) at Te (react-dom.production.min.js:146)
if I change the entries that I'm viewing to 100 which is more all that all I have this doesn't happen. **
Adding key to that table with the data.length as the key works great.

I don't know what you have in subscptionOrders array but I think if error about keys is empty that maybe is a problem with that. I will check this with dummy data because I'm doing refactor at the moment so if it's a problem with that I will try to fix that as soon as possible.

So the problem happens exactly when we filter on an entity on the object which is status then it crashes. But if the table is set to 100 entities to view then it works fine. I'm not sure if it's a problem with paging and the table not being able to preform componentDidUpdate
