I have this Apply to Each where i need to get the Length() of a sharepoint single line of text field:-

But I am getting this error:-

Unable to process template language expressions for action 'Condition_2' at line '0' and column '0': 'The template language expression 'length(outputs('Get_items_2')?['body/value']?['Project_x0020_name'])' cannot be evaluated because property 'Project_x0020_name' cannot be selected. Array elements can only be selected using an integer index. Please see https://aka.ms/logicexpressions for usage details.'.

although the "Project_x0020_name" is an accurate field inside the list.

Any advice?

Hi,

Small thing you have missed here- you are iterating through values dynamic content , and each element you are trying to iterate through is a list item which should be represented as items('Apply_to_each_2')?['Project_x0020_name']

So correct expression to be used is length(items('Apply_to_each_2')?['Project_x0020_name'])

Mark it as solution if it resolves your query !

Thanks & Regards,

First, I'd recommend just deleting your condition and replacing it with a filter.

Use
outputs('Get_items_2')?['body/value']

as the input to the filter, and use

length(item()?['body/value']?['Project_x0020_name'])

as the first part of the filter and after the greater than operator put "26"

But yes, if you want to fix what you have follow use:

'length(item()?['body/value']?['Project_x0020_name'])'
