Thanks for reporting. This is a known issue that will be resolved in the next Vaadin 23.6 version.
The current workaround should be adding the following overrides in package.json

"typescript": "6.0.3",
"@types/node": "26.0.1"

How is it possible to suddenly start failing? I guess it was not failing when the version was released …

Actually, the correct fix seems to be pinning “@types/node”: “18.19.115.” Sorry for the confusion.

This is the fix applied to the next 23.6 release

I guess some transitive dependency caused a newer @types/node package to be used

Do you have an overview of the Vaadin versions that are affected?

6

Do you have the corresponding Vaadin ticket for me?

We spot the issue only on 23.6 (EOL, requires a commercial license); older 23 minors are not supported anymore.
No ticket, unfortunately. The PR was created based on an internal discussion.
