The frontend is crashing with the following error:

TypeError: Cannot read properties of undefined (reading 'setAttribute')
    at <unknown> (.next/server/chunks/707.js:1:837)

The payment is not crashing, but no OTel data is being sent.
I do see logs like:

{"level":"info","time":1750157799195,"pid":1,"hostname":"ac022eeb90b9","service.name":"payment","transactionId":"42c3bad6-103e-4fbf-9d68-08d7b4a5c416","cardType":"visa","lastFourDigits":"3547","amount":{"units":{"low":1443,"high":0,"unsigned":false},"nanos":699999994,"currencyCode":"USD"},"loyalty_level":"bronze","msg":"Transaction complete."}

But the traces are exported.

Flagd-ui seems to be working fine.

Hey @Red-GV sorry for taking that long to review.

[Red-GV]

No problem at all @julianocosta89 . I'll try to take a look at what's going on later this week.

[Red-GV]

Haven't tested these changes yet, but wanted to update this branch in the interim.

Heads up @julianocosta89 , I've cherry-picked a commit from this PR into another PR. I believe this commit should fix the problems with the building of the protobuf files and allow the Dependabot's attempt to update the packages to at least go into the building state.
