That kind of error is obtained when you try to get data from a Json and the logic you use to extract the data does not match with the structure of the json
Here is an example of how you can get data from Airtable using the GetAllRows block (with this block you get a Json in the response content) using dictionaries
Note: In airtable it is easier to get each column and then work with those data as lists
This is my Airtable structure:
We create the variables for each airtable column. Note that when you get a Json, you must always get two data that are always the same, which are id and fields:
(In the end I create a result variable to put everything there)
Then with these blocks you get the data from the Name column and the data from the City column:
The foreach block puts the data in a list (result) and it´s displayed on a label
This is the result:
