Question

Any time I try to write unit tests for a flow with mapped tasks I am getting a `MappingLengthMismatch` with the following traceback ```Parameters for map must all be the same length Got lengths args 0 kwargs 2 ``` However all of the parameters for the task do have the same length

For example The task I m testing is `load` and it takes a parameter called `sync` ```loads = load map sync= data usage per cycle sim status device change history expected start time=unmapped expected start time ```

The array passed to `load` contains ``` Pdb data usage per cycle schema table1 data here Pdb sim status schema table2 data here Pdb device change history schema table3 data here ``` A list of tuples
