Invalid argument type in power automate (using power fx)

(0) ShareShare
ReportReport
Posted on by Cristian_Melo

Hi everyone.

 

I'm new to the world of power apps and power automate.

and for this reason  I chose to use the Power Fx language to make basic codes.

 

PROBLEM: When I import a DataTable (no matter the source) and I want to perform operations, I usually run into the same "Invalid Argument type" error. I usually use funtions like as Lookup, search, filter and all those that work to manage the DataTable. I don't know how to fix this problem.

 

I've tried with every example from the main page, but I don't know if the trouble is in how I Type  the logical_test, or the way that I type the column. I attach 3 files to explain better the problem

 

I appreciate any possible help.

    Hi @Cristian_Melo ,

     

    Power Fx in PAD still in preview state ,so we don't recommend you to use it in Production or development.

    Please Disable the Power Fx option  as shown in below image and try Creating same flow it will work.
