Reproduction

1. Install [email protected]
2. Deploy to Azure App Service, Node 20.x LTS

Additional context

Build fails when deploying to an Azure App Service (docker container). The docker command run by deployment:

docker run -d --expose=8080 --name ***_0_e74571c2 -e WEBSITE_USE_DIAGNOSTIC_SERVER=true -e WEBSITE_SITE_NAME=*** -e WEBSITE_AUTH_ENABLED=False -e WEBSITE_ROLE_INSTANCE_ID=0 -e WEBSITE_HOSTNAME=***.azurewebsites.net -e WEBSITE_INSTANCE_ID=*** -e HTTP_LOGGING_ENABLED=1 -e NODE_OPTIONS=--require /agents/nodejs/build/src/Loader.js appsvc/node:20-lts_20240619.2.tuxprod npm run start-uat

Downgrading to 3.0.1/3.0.0 did not resolve

jwks-rsa version

3.1.0

Node.js version

20.14.0

Workaround found: Open the remote server via Kudu tools/SSH and navigate to www root...

1. rm -rf node_modules
2. rm -f package-lock.json
3. npm install

Honestly unsure where to solve this issue. If a dependency version update here isn't the solution, perhaps best I move this to Azure or lru-memoizer.
