Hello,

I am using Upload a file or Image Dataverse Action to create a file in dataverse.

Here are the ways I've used to fill in the Content field:

{
"$content-type": "application/pdf;base64", // also tried without "base64" 
"$content": "JVBERi0xLjMNCjEgMCBvYmoNClsvUERGIC9UZXh0IC9JbWFnZUIgL0ltYWdlQyAvSW1hZ2VJXQ0KZW5kb2JqDQo0IDAgb2JqDQo8PCAvTGVuZ...=" // also tried without using quotes
}

{
"$content-type": "application/pdf;base64", // also tried without "base64"
"$content": "@{base64ToBinary(JVBERi0xLjMNCjEgMCBvYmoNClsvUERGIC9UZXh0IC9JbWFnZUIgL0ltYWdlQyAvSW1hZ2VJXQ0KZW5kb2JqDQo0IDAgb2JqDQo8PCAvTGVuZ...=)}"
}

The pdf is always empty.

I've checked the base64 string in an online base64 to PDF convertor and it is correct, it produces a pdf file.

Any help would be much appreciated.

Hi @Iro_ how are you?

@Iro_ could you please provide an image from your flow? What actions are using? Where the file comes from?

I did a small sample here creating the column and also an instant flow passing a file as argument, and it worked

Hello @rohentz

Here is an image from the flow:

The file is in base64 string format and I get it from a child flow.

Thank you

Yes, I've already tried to add the text directly.
In that case, the file does not even open:

Hi @Iro_ now it worked and the file opened with no issues.

Add a compose and use the base64ToBinary function. As parameter pass the file content that you have

JVBER .....

Add the output from compose to the content parameter
