Hey everyone, i've been stuck for a while now on this issue im having where when i want to deploy my java app to azure it doesnt recognise the artifact that i build in a previous workflow run. these are the build and deploy files:

name: Build JAR app - kobeodbCR-backend

on:
  push:
    branches:
      - main
  workflow_dispatch:

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v4

      - name: Set up Java version
        uses: actions/setup-java@v1
        with:
          java-version: "17"

      - name: Build with Maven
        run: mvn clean install

      - name: Upload artifact for deployment job
        uses: actions/upload-artifact@v4
        with:
          name: java-app
          path: "${{ github.workspace }}/target/*.jar"

name: Deploy JAR app to Azure Web App - kobeodbCR-backend

on:
  workflow_run:
    workflows: ["Build JAR app - kobeodbCR-backend"]
    types:
      - completed

jobs:
  deploy:
    runs-on: ubuntu-latest

    steps:
      - name: Download artifact from build job
        uses: actions/download-artifact@v4
        with:
          name: java-app

      - name: Deploy to Azure Web App
        id: deploy-to-webapp
        uses: azure/webapps-deploy@v2
        with:
          app-name: "kobeodbCR-backend"
          slot-name: "Production"
          package: "*.jar"
          publish-profile: ${{ ... }}

and this is the error im getting:

deploy

For more information, visit the GitHub Artifacts FAQ: https://github.com/actions/toolkit/blob/main/packages/artifact/docs/faq.md

does anyone have an idea on why this is happening?
the build workflow completes successfully, and the artifact is created, but the deploy workflow fails after give or take 10 seconds
