@Anonymous

I think this seems to be issue from power automate

Actually I have developed one custom action and was able to use once in PAD
But after some days, when I tried reinstalling the same module it shows the same error for me

But it wasn't occuring for all cases

Could u give some information about the code you have developed ?

Hi @Nived_Nambiar and @ClavinFernandes

Thank you for the reply.

My Environment :
Windows 11
Visual studio 2022 (LTSC 17.6).
Power Automate version : 2.34.187.23206

Here I have attached my source code. After developed the source code .
I signed the generated .dll file with a trusted certificate.
I packed the generated .dll file along with all its dependencies in a .cab file.
I signed the .cab file.
Thank you

Hi @Nived_Nambiar ,
In this forum community, can you tag this who are familiars with the PAD and PAD people from Microsoft? Because I am very new in the forum.

Hi @Anonymous

Sorry for late response

You have followed correct steps to create custom action.

Currently I don't have access to my laptop to try your case. Even I am looking for the reason behind the same error as this is a weird issue.

Let me tag few more experts in Power Automate Desktop

@Agnius @MichaelAnnis @VJR @ClavinFernandes

I know Clavin has recently given a session on creating custom action so he can help you around for this
