Invalid expression when trying to shorten a file name

I’ve created a variable called FullFileName and I now want to use an expression to say - if the file name is greater than 155 characters, take the first 155, otherwise take the whole name.

 

Getting an error saying the expression is invalid, can anyone spot what I’m doing wrong?

 

if(greaterOrEquals(length(triggerBody()? variables('FullFileName')), 155), substring(triggerBody()? variables('FullFileName'), 0, 155), triggerBody()? variables('FullFileName'))

Hi @gm355 ,

 

You could take a try with expression below:

if(greater(length(variables('FullFileName')),155),substring(variables('FullFileName'),0,155),variables('FullFileName'))

I have made a test on my side, please refer to screenshot below to create the flow:

The expression in the Compose as below:

if(greater(length(variables('FullFileName')),5),substring(variables('FullFileName'),0,5),variables('FullFileName'))

 

The flow would run successfully as below:
