Specify the language of the codelab if it is not English:

In which task and step of the codelab can this issue be found? Step 8

Describe the problem The code in Step 8, part 7 doesn't accurately portray the progress from the previous step (Step 7). In Step 7, in the MarsViewModel.kt file, the getMarsPhoto() function launches a coroutine, and puts the result of the try-catch block into the marsUiState variable. However, this doesn't match the code shown in the codelab, as it assigns the value of the marsUiState variable inside the try-catch block, The discrepancies in this code shown versus following the progress from the previous steps can lead to an error (type mismatch).
