Maybe there is someone in this forum who is well versed with both Power Automate and Business Central.

I'm using a Power Automate flow to send file attachments from a Dataverse File Column to Business Central. The flow works good, but the problem is that when i try to open the file in Business Central, its corrupted, and i can't view it. I believe something is wrong with the base64tobinary function. Any ideas?

Here is part of how I get the file from Dataverse:

The full Compose 1 Inputs: decodeBase64(body('Download_a_file_or_an_image_1')?['$content'])

And how I attach this in Business Central:

The full Content: base64(body('Download_a_file_or_an_image_1'))

Hi, can you get this file directly? I also suspect that it is a problem with Decode in PowerAutomate. I have tried to get the file directly before and it can be transferred to BC.

If you can only pass Base64, you can consider using the function in BC to convert. Add a new field to save Base64 data. When the field is validated, it is automatically converted to the file. This is done in AL.

For example,

Hope this helps.

Thanks.
