Not really possible to be sure given that you haven't shown us any
real code, but my wild guess would be that you're iterating over
something using a for loop, and the loop variable has the wrong type
to hold one of the arguments. For example:
for item in values({ 'x' : [ 1, 2, 3 ], 'y' : 1 }) | echo item | endfor
leads to
[1, 2, 3]
E706: Variable type mismatch for: item
because 'item' is a List after the first iteration, but needs to hold
a Number on the second iteration. You can get around this by calling
':unlet item' before the :endfor
