ansible mount module can't find special device

I'm trying to get ansible to mount my attached and formatted hard drive located under /dev/vdb/ to /data. This is the playbook section:

---
- name: setup dada2 
  hosts: tnt
  remote_user: ubuntu
  become: yes
  become_method: sudo

  tasks: 
    - name: Create the file system
      filesystem:
        fstype: ext4
        dev: /dev/vdb

    - name: Mount the created filesystem
      mount:
        path: /data
        src: /dev/vdb/
        fstype:  ext4
        state: mounted

    - name: Make /data available for everyone
      file:
        path: /data
        state: directory
        mode: 0775

However, I get the error message: 

TASK [Mount the created filesystem] ********************************************
fatal: [x.x.x.x]: FAILED! => {"changed": false, "msg": "Error mounting /data: mount: /data: special device /dev/vdb/ does not exist (a path prefix is not a directory).\n"}

but /dev/vdb does exist and running sudo mount /dev/vdb /data works fine. Any ideas what could be the reason for this? I have no experience with /etc/fstab, but the name occured often so I had a look into it. It says: 

LABEL=cloudimg-rootfs   /        ext4   defaults        0 0
LABEL=UEFI      /boot/efi       vfat    defaults        0 0
/dev/vdb/ /data ext4 defaults 0 0

Any ideas on this one?

EDIT:

A similar error was described here: Error in Mount Module in Ansible, but I set the fstype as suggested and I would not know what entry I would have to add to fstab and how?

The problem is the trailing slash in /dev/vdb/

- name: Mount the created filesystem
  mount:
    path: /data
    src: /dev/vdb/
    fstype:  ext4
    state: mounted

Correct

- name: Mount the created filesystem
  mount:
    path: /data
    src: /dev/vdb
    fstype:  ext4
    state: mounted

Remove the line from /etc/fstab manually 

/dev/vdb/ /data ext4 defaults 0 0
