Join data transformation doesn't work with single query

OS info

  • Operating System : Windows 10.0.19042
  • Wappler Version : 3.9.3

Problem description

Single query returns an object and not an array. Join data transformation expects arrays.

“Undefined property: stdClass::$group_id”

Steps to reproduce

  1. Create a single query.
  2. Create a second single query.
  3. Add the Join data transformation step.

It maybe is not documented that good, but all the data transformations only work on collections/arrays. A workaround would be to just not use single query but use the mutliple records and limit that to 1.

Would it be possible to hide or make it not possible to select single query?
