Pass image object from power apps to power automate flow

[MeSan]

Hi everyone I hope you're doing well,

I've built a flow in which I have a simple power app as a trigger, then a populate word document step and after that a step to convert the populated document into pdf and lastly a step to send an email. Here is the structure :

I have an image field to populate in the word document and I gave it as a parameter askinpowerapps, but when I run the flow in the power app I get this error : The image is not of type PNG or JPG. Please provide an image of type PNG or JPG.

I know that power apps only returns me the reference to a cached image, not the image itself. But I have no idea how to directly get the image object from the power app, is it hidden somewhere in the app so I can access it ?

PS: My image is in a SQL Server table and was declared this way :

And whenever I add a new item through the power app to this table, I upload an image file as well and it is stored like this in my table :

Can anyone help me with this please I'll highly appreciate

Thanks in advance !

Hello @Achavan ,

Yes this sounds a nice solution but when I want to set the variable I don't see the image field in the list :

Do I need to do a specific configuration ?

Thanks in advance.

[Achavan]

First you have to initialize variable of type object -

[MeSan]

Okey thanks @Achavan 

I don't understand where this variable comes from :

do I need to define it somewhere ?

[Achavan]

in your case, you have to add this output  0xFFD.......... 

[MeSan]

Okey but when I try to save the flow I get this message :

and previously no error was mentioned 😕

Any idea where does this come from ?

[MeSan]

[Achavan]

Yes @Achavan  I use it in the populate image field :

But I'm getting a strange error while trying to save the flow :

I can't save the changes..

Where does this come from plz ?

[Achavan]

can you please share output expression ?

[MeSan]

@Achavanthe outputs function has as parameter an "ask in power apps" which is supposed to be the image reference :

And I should pass it to to flow button when linked with the power app. Is this the right way of doing it ?
