OH 4.0.1 on Debian 12 Proxmox VM using ECMAScript 11
Took me a bit to find the cause of this error:

Found the mention of sendCommand in my remark to be the cause, looks like the compiler is not skipping the remarks:
//Wait 500ms for sendCommand to update the state of the item
Noticed that the new ECMAScript 11 on OH 4.0.1 is economic with providing the line/position of an error and took me a bit to find the reason for this error as remarks was not where I was looking. When testing scripts I look in the openhab.log, is there possibly another way to get more detailed error information as with ECMAScript 5.1?
