[CAP] BAS – port 4004 is already in use by another server process

If the default port 4004 is already open and you want to see what is bound to it, select View -> Find Command -> Ports Preview

Solution to kill another “watch.js” process using/blocking the port: https://answers.sap.com/questions/13016130/sap-business-application-studio-stop-running-serve.html
To archive the same in a single command use:

lwctl -c basic-tools kill -9 $(lwctl -c basic-tools ps aux | grep watch.js | awk '{print $2}')

As alternative, change the default port by adding a new port in package.json to the start script, for example: “start”: “cds run –port 4003” and use npm run start instead of cds watch.

[CAP] Query teamMembersSize from SuccessFactors

const sfsfSrv = await cds.connect.to('sfsf')

// Option 1: Query Notation
const response = await sfsfSrv.run(SELECT`teamMembersSize`.from`User`.where`userId = ${req.user.id}`)
console.log("option 1: " + response[0].teamMembersSize)

// Option 2: HTTP method-style
const response2 =  await sfsfSrv.get(`/User('${req.user.id}')/teamMembersSize/$value`)
console.log("option 2: " + response2)

[CAP] Easy way to test if your approuter is working

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.

[Git] Error on Windows using VSCode Dev Container

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.
