Blob data type for device attributes format issues

Just looking for some guidance on using the blob data type for attributes on devices. Trying to store a base64 encoded string (longer than the 1023 string max) using the workflow Device:State node. Looking at the Device Log I can see the following error message: The data for a provided attribute is not valid for that attribute's data type.
I have tried various different content type but not having any luck and figured you guys could point me in the right direction. thanks

@cam415,

Welcome to the Losant Forums!

Would you be able to provide a screenshot of this error and an example of the data you’re trying to report as a blob attribute?

Just to help out in the meantime, when reporting Blob Data from a workflow you may use the base64Encoded helper to re-encode your UTF8 string to base64:

{{{encodeBase64 working.imageData}}}
