Array elements can only be selected using an integer index.

Unable to process template language expressions in action 'Compose_2' inputs at line '0' and column '0': 'The template language expression 'length(outputs('Get_items')?['body/value'])' cannot be evaluated because property 'body/value' cannot be selected. Array elements can only be selected using an integer index.

I am trying to get the length of an Array from from apply each loop: length(outputs('Get_items')?['body/value'])

Any help please

Hey @abeyenen72

The error you are getting is because you have a loop(Apply_to_each_2) and then get items inside it.

Because of this the get items is running twice.

So the expression you are using outside doesnt know which iteration's length you need.

So, you want the combined length of both the get items or separately.

To get combined length:

First initialize an integer variable.

Then inside the apply to each use action increment variable. In that write the above expression.

This will calculate length for all the iterations.

Then outside you can use a compose and add the variable in it and it will show you the combined length of array:

I hope this helps 🙂
