Hello everyone,
I'm encountering an issue with a Microsoft Power Automate workflow where recipients are unable to open an email attachment sent via the workflow. I would greatly appreciate any guidance or suggestions from the community. Here's a brief overview of the problem:
Issue Description: In my workflow, I'm using the SendEmailV2 action to send an email with an attached file. The email is sent successfully, and the attachment appears to be included, but recipients are unable to open the attached file.

Workflow Configuration: Here's the relevant part of my JSON configuration:
{
"type": "OpenApiConnection",
"inputs": {
"parameters": {
"emailMessage/To": "example@example.com",
"emailMessage/Subject": "testing",
"emailMessage/Body": "<p>testing</p>",
"emailMessage/Attachments": [
{
"Name": "@item()?['{FilenameWithExtension}']",
"ContentBytes": "@{base64(body('Get_file_content'))}"
}
],
"emailMessage/Importance": "Normal"
},
"host": {
"apiId": "/providers/Microsoft.PowerApps/apis/shared_office365",
"connection": "shared_office365",
"operationId": "SendEmailV2"
}
},
"runAfter": {
"Get_file_content": [
"Succeeded"
]
}
}
I'm wondering if there's something I'm missing in the configuration or if there's a known issue with this kind of setup. Any insights, suggestions, or pointers to relevant resources would be greatly appreciated!
Thank you in advance for your help!
