npm install failed after upgrade to Debian 11

[juha-h]

I upgraded my host OS from Debian 10 to 11 and noticed that npm install does not anymore succeed. I got

$ npm install

From page https://www.npmjs.com/package/react-addons-css-transition-group I learned that now react-transition-group is recommended as react-addons-css-transition-group replacement. So I went and in package.json replaced line

"react-addons-css-transition-group": "^15.6.2"

with line

"react-transition-group": "^4.4.2"

and in lib/components/TransitionAppear.jsx line

import ReactCSSTransitionGroup from 'react-addons-css-transition-group';

with line

import ReactCSSTransitionGroup from 'react-transition-group';

After that npm install worked (with lots of depreceted warnings):

Then I run gulp prod and got two errors about json file extensions:

I haven't tried to figure out how those errors could be fixed.

The json errors are produced by lint, so I guess they are not important.
