An easy way to test your approuter is using the user-api-service. For that add the following route to your xs-app.json
{
"source": "^/user-api(.*)",
"target": "$1",
"service": "sap-approuter-userapi"
}
And after deployment, open the application router URL and add /user-api/currentUser to it. You should see your Email and other User details. This is testing that the application router is actually getting the security token from the UAA instance.
After connecting to a local dev container using Visual Studio Code and trying to clone a private project from Github I got the following error:
Cloning into 'myProject'...
warning: url has no scheme: helperselector
fatal: credential url cannot be parsed: helperselector
The only way I could remove this error was deleting the helperselector settings. So open the git config with:
git config --edit --global
and remove the the helperselector block (the first two lines). You will now get asked again for your credentials when cloning a project.

const buffer = Buffer.from(myBase64File, "base64")
const base64 = buffer.toString("base64")

Heute gelernt, dass neben dem wohl verbreiteten Plural “die Teelichter”, auch “die Teelichte” richtig ist. 🙂

And again… a Nextcloud upgrade failed. After a docker-compose pull and docker-compose up -d the maintenance mode won’t turn off. So I tried to turn it off manually, but I still couldn’t finish the update via WebGUI. I also couldn’t find any errors via the log.
docker exec --user www-data nextcloud-app php /var/www/html/occ maintenance:mode --off
So I triggered the upgrade again from the terminal and finally got an exception.
$ docker exec --user www-data nextcloud-app_1 php /var/www/html/occ upgrade
Nextcloud or one of the apps require upgrade - only a limited number of commands are available
You may use your browser or the occ upgrade command to do the upgrade

Quick search on google and it seems that the image for 21.0.8 is broken and already withdrawn. Here and here. Great if users can still pull it from the docker repo…
I disabled the user_ldap addon via command line. This site helped me finding the right commands. After another occ upgrade and a few minutes, the instance finally came back online.
docker exec --user www-data nextcloud-app php /var/www/html/occ app:list
docker exec --user www-data nextcloud-app php /var/www/html/occ app:disable user_ldap
docker exec --user www-data nextcloud-app php /var/www/html/occ maintenance:mode --off
docker exec --user www-data nextcloud-app php /var/www/html/occ upgrade
In the end I also stumbled across the official nextcloud blog, where they announce 20.0.9 and that they had problems with 20.0.8…. But if the new docker image is not yet provided, and you can’t downgrade from your broken 20.0.8 back to 20.0.7, this doesn’t help you at all.
https://github.github.io/fetch/#Headers
const response = await fetch("https://example.com/api")
for (const [key, value] of response.headers) {
console.log(key, value)
}
An alternative would be forEach()
response.headers.forEach((value, key) => {
console.log(value, key)
})
Or using the entries() iterator (ES8)
const headerIterator = response.headers.entries()
console.log(headerIterator.next().value)
console.log(headerIterator.next().value)
To add a new header just use set()
response.set(key, value)
const animals = [‘cat’, ‘dog’, ‘horse’]
// before
const lastItem = animals[animals.length - 1]
// ES2022
const lastItem = animals.at(-1)
const sBase64 = "JVBERi0xLjQKJcOkw7zDtsOfCjIgMCBvYmoKPDwvTGVuZ3....."
const arrayBuffer = new Uint8Array([...window.atob(sBase64)].map(char => char.charCodeAt(0)))
const fileLink = document.createElement('a')
fileLink.href = window.URL.createObjectURL(new Blob([arrayBuffer]))
fileLink.setAttribute('download', "example.pdf")
document.body.appendChild(fileLink)
fileLink.click()
Or use the npm package FileSaver.
import { saveAs } from "file-saver";
const sBase64 = "JVBERi0xLjQKJcOkw7zDtsOfCjIgMCBvYmoKPDwvTGVuZ3....."
const buffer = Buffer.from(sBase64, "base64") //Buffer is only available when using nodejs
saveAs(new Blob([buffer]), "example.pdf")
