Hi @Shahin_Akhter

You should remove the @ before length.
Regarding the usage of length, I think this link will help you:

Hi Levi,

Thanks for the response.
I have tried that earlier, didn't work. This error appears whenever i try to parse the output/ body of the previous step

Hi @Shahin_Akhter

You should fill in the correct parameter in length.
The purpose of the length function is to return the number of items in the array, so you should refer to an array in length.

Hi Levi,
This is what I tried now -
length(outputs('Html_to_text')).
Still the same error. Not sure if I am missing any syntax in the exprssion.

Hi Levi,
My issue is the error appear whatever function I use to process - outputs('Html_to_text') from previous step.
Like even split(utputs('Html_to_text')).

Hi @Shahin_Akhter

The length function can also be used to check the string length, your problem is a wrong reference to Html to text.
