Deploying an image doesn't work

I am trying to deploy an image to Lambda, but I keep getting critical errors. I think I am using the action properly, this is my .yml:

name: Deploy to Amazon Lambda

on:
  push:
    branches:
      - "master"

jobs:
  deploy:
    name: Deploy
    runs-on: ubuntu-latest
    environment: production

    steps:
      - name: default deploy
        uses: appleboy/lambda-action@master
        with:
          aws_access_key_id: ${{ secrets.AWS_ACCESS_KEY_ID }}
          aws_secret_access_key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
          aws_region: eu-central-1
          function_name: test2
          handler: handler
          memory_size: 500
          timeout: 10
          role: test2-role-t8u20e4g
          image_uri: <account>.dkr.ecr.eu-central-1.amazonaws.com/<repo>:latest

However, I am getting:

I have already double-checked that my IAM user has full admin access (just for testing), I am not sure what is wrong.

Any suggestions?
