Re: Posting image with adaptive card - Error in JSON
Hi , @Thinzar
First you need to check if your Message is correct in your side . You can copy it here to test:
Designer | Adaptive Cards
And i test it in my side , it works good like this:

base64(outputs('Get_file_content_using_path')?['body'])
{
"type": "AdaptiveCard",
"$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
"version": "1.4",
"body": [
{
"type": "ColumnSet",
"columns": [
{
"type": "Column",
"width": "stretch",
"items": [
{
"type": "Image",
"url": "data:image/png;base64,xxxxxxx"
}
]
}
]
}
]
}
