Git Bash can't find node.js, even though it is in my Path and it works in Powershell

I'm having trouble using Node.js on Git Bash (on Windows 11). When I run

npm install --save puppeteer

or a similar command, I get the following error message:

npm ERR! code 1
npm ERR! path C:\Users\{user}\git-repos\book-scraper\node_modules\puppeteer
npm ERR! command failed
npm ERR! command C:\WINDOWS\system32\cmd.exe /d /s /c node install.js
npm ERR! 'node' is not recognized as an internal or external command,
npm ERR! operable program or batch file.
npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\{user}\AppData\Local\npm-cache\_logs\2022-08-18T20_26_25_630Z-debug-0.log

I double checked that Node was included in my Path variables. I have tried including both path to the node directory and to node.exe. When I run the same command in a Powershell or Windows Terminal the command works without issues. I also checked the log - here is the relevant part of the log file:

365 verbose pkgid puppeteer@16.1.1
366 verbose cwd C:\Users\{user}\git-repos\book-scraper
367 verbose Windows_NT 10.0.22000

374 error 'node' is not recognized as an internal or external command,

I'd appreciate any help anyone can offer!
