As off today, a script that has always worked, now suddenly throws an error … ❌ Script Error ⚠ ReferenceError: Buffer is not defined at connectToWallbox (wallbox.js:25:35) at wallbox.js:131:19 at processTicksAndRejections (node:internal/process/task\_queues:96:5) I am running Homey 7.4.1 and HomeyScript v3.3.0. Restarted HomeyScript and also have restarted Homey. No change. No other installs etc done. ---

I think it helps when you share the script with us? ---

I don’t see why. Buffer is a global variable set by homeyscript. Now it is not defined anymore. Why do you need the script? If you think it’might help, but I don’t see how : [Wallbox Pulsar plus charger lock/unlock pause/resume](https://community.homey.app/t/wallbox-pulsar-plus-charger-lock-unlock-pause-resume/54616) ---

I’m not sure how your script ever worked because nothing has been updated that could cause your issue as far as I can see. However you can update your script to at least work again with this: ```auto const Buffer = this.constructor.constructor("return Buffer")() console.log(Buffer.from('test')); ``` ---

I disagree: 3.2.6 14 okt. 2021 Added `Buffer` to global scope. ---

You are right I could not see this in the source. I think there has been a publish of the app without the source being saved. Meaning the next version does not have the Buffer change with it. ---

That was quick! Buffer is back, thanks!
