Dear maintainer:

During a rebuild of all packages in unstable, this package failed to build.

Below you will find the last part of the build log (probably the most
relevant part, but not necessarily). If required, the full build log
is available here:

https://people.debian.org/~sanvila/build-logs/202609/

About the archive rebuild: The build was made on virtual machines from AWS,
using sbuild and a reduced chroot with only build-essential packages.

If you cannot reproduce the bug please contact me privately, as I
am willing to provide ssh access to a virtual machine where the bug is
fully reproducible.

If this is really a bug in one of the build-depends, please use
reassign and add an affects on src:ipywidgets, so that this is still
visible in the BTS web page for this package.

Thanks.

This seems to have been introduced by node-base64-js
1.5.1+dfsg+~1.5.0-1, where the only substantial change was to replace
@types/base64-js with a stub.  Xavier, can you advise what the right fix
in ipywidgets would be?

Thanks,

Control: reassign -1 node-base64-js 1.5.1+dfsg+~1.5.0-1
Control: affects -1 src:ipywidgets

This turns out to be a bug in node-base64-js.  I've filed
https://salsa.debian.org/js-team/node-base64-js/-/merge_requests/1, and
verified that ipywidgets builds with that fix.  Please could somebody in
the JS team apply this?

Thanks,
