@gil-gross-glbe thanks we'll take a look into this. I'm assuming this is happening in a normal browser environment? does this still occur if you turn off replays sampling?

can you email me with your org slug? billy at sentry.io -- I'd like to take a look into your account and make sure these errors get credited back to your account, as this shouldn't happen.

Hi @gil-gross-glbe!

So in this case the error does not actually occur in the SDK itself but rather in your application code on <anonymous>:1:1182 – which is just wrapped by our SDK. Could you check if you can find this part of your bundle?
