When embedding QML charts QField fails evaluating expressions containing line breaks

[lp-dj]

The attached code code_with_linebreak.txt is rendered correctly in QGIS in a QML widget as a bar chart. In QField all bars remain empty.

After some (much) trial and error I realized that QField has problems with line breaks within an expression.evaluate().

The - in my eyes a bit more difficult to read - code code_without_linebreak.txt is now also rendered correctly in QField

Is this already a bug? Would I have had a chance to find out somewhere about the syntax QField needs to get the same result as QGIS?

With many thanks and best regards

By the way: Is there actually a way to use the "array_foreach" function in a nested manner in order to significantly reduce the code (e.g. like here: array_foreach_nested.txt )? If so, how do I refer specifically to the @element of the different levels?
