placeholder of ip xxx.xxx.xxx.xxx/28 is calculated as a division

[MalfuncEddie]

I retreive IP's by rest api in the form of xxx.xxx.xxx.xxx/28 but the placeholder is calculated and cast to int ;(

 - name: server_ip_tmp
    type: enum
    label: IP
    expression: fn.fnRestAdvanced( 'get',
      'url','',{}, '[.[]]')
    columns:
      - address
    valueColumn: address
    noOutput: true

  - name: server_ip
    type: expression
    label: IP
    expression: "'$(server_ip_tmp)'.split('/')[0]"
    runLocal: true
    hide: true

What am I doing wrong?

some code /headers/url censored

You are pointing to $(server_ip_tmp) => is that multicolumn ? It will by default point to column 1 (could be an ID)
Point either to $(server_ip_tmp.address) or set placeholderColumn: address
