`$haystack` can not be interpreted as string¶

Most often, the reason for this error is a wrongly defined TCA column. For example something like this (duplicate nesting of items):

'items' => [
   'items' => [
       ['noRotation', 0],
       ['oneQuarter', 1],
       ['halfCircle', 2],
       ['threeQuarter', 3],
  ],
],
