Hi @Riccardo_Sesto , thank you for your post.
Just basing this on your 2 images and what I see as advice in Mikael's blog.
He says to use:
dataUriToBinary(triggerBody()['Createfile_FileContent'])
Your error suggests you use "Create_Nomefile" as "Createfile_FileContent" doesn't exist (within your Compose).
Should you maybe be using the following within your Compose?
dataUriToBinary(triggerBody()['Create_Nomefile'])
I say this as the first image you post of the error suggests the compose has "Createfile_FileContent", whilst the second image i can see you are using dataUriToBinary() but not sure what is in there ...
Maybe you can confirm the full expression within your compose and post back if my information hasn't helped.
Please let us know if this helps at all?
If you have found my post helpful, please mark thumbs up.
Any other questions, just ask.
Thanks, Alan
