Question

I am getting ` FunctionTask object is not iterable` error Can anyone point me out what it is

Jeremiah · Answer

Hi < Akshay Verma> it sounds like you are trying to iterate over a task or possibly the result of calling a task which is also a task Hard to say without more code can you provide an example

Akshay Verma · Answer

i am doing the following ``` task def generate context level data mlsi lvnr tol ml ci = td split clv mlsi lvnr tol return ml ci td input = a 1 b 2 c 3 with Flow TD as flow td input = Parameter td input context level ml context level ci = generate context level data td input a td input b td input c ```

Jeremiah · Answer

Ah ok it s because you are assigning the result of `generate context level data` to two variables `context level ml` and `context level ci` but Prefect doesn t know what the result of `generate context level data` is so Python can t do that unpacking

Jeremiah · Answer

Try this instead

Jeremiah · Answer

``` context result = generate context level data context level ml = context result 0 context level ci = context result 1 ```

Jeremiah · Answer

Python will let us index an unknown object like `context result` but not unpack it

Jeremiah · Answer

Note I can t promise this will work exactly as written because it depends on what is actually coming out of `generate context level data` but this pattern should work return a single object from your task then index it appropriately
