I have a case where I need to refer to a value in JSON
body('Parse_JSON_product')['values']['Media_Pictrue_Main_1'][0]['_links']['download']['href'].
I do this with an expression that I assign to a variable. However, I have a problem because ['Media_Pictrue_Main_1'] can have different values, e.g. ['Media_Pictrue_Main_2'], ['Media_Photo_Main_1'], ['360Photo']. How to insert a variable into an expression? I tried this:
body('Parse_JSON_product')['values']['@{body('Parse_JSON_2')?['media']}'][0]['_links']['download']['href'],
but I get an error expression when I try to save.
I tried the compose element and then using it in the expression for the variable, but that didn't help either.
Hi Rafał Lesiński,
To replicate and test your flow, can you share me the below information?
With that I can help you to build your expression.
Remember that the expression on flow start with @{ So you don't need to include the @ variable on your expression again.
Let me know your response. Luis
@Rafał Lesiński In case if you are still facing the issue then please share your sample JSON object and what value is expected from the JSON object. As per your screenshot you are expecting the value of href property but to assist you would be needing the sample JSON object to validate your expression.

The problem is that I have already worked around this problem and it is not possible to reproduce this problem in my example. I will create another example and send it. Sorry for the delay.
