Upload file via Ice.BO.AttachmentSvc/UploadFileToDocTypeStorage

I want to use below service in Automation Studio (Workato) to upload a file in GoogleStorage:

api/v1/Ice.BO.AttachmentSvc/UploadFileToDocTypeStorage

But I got the error:

{
“code”: 500,
“message”: “500 Internal Server Error”,
“body”: “Sorry! Something went wrong. Please contact your system administrator. Correlation Id: e4cdc7c2-7c8d-4e50-bdf7-d65f1a513d5e”,

}

My input request is:

Data:
{
Doc type ID: “Image_At”,
Parent table: “HDCase”,
File name: “crm_read_email-05.jpg”,
Data: “/9j/4AAQSkZJRgABAQEAYABgAAD…”,
Metadata: null
}
}
}

Has anyone seen this problem before?

what is the exact error in the server’s event viewer?
also, do these key names really contain spaces, or it is just formatting?
{
Doc type ID: “Image_At”,
Parent table: “HDCase”,
File name: “crm_read_email-05.jpg”,
Data: “/9j/4AAQSkZJRgABAQEAYABgAAD…”,
Metadata: null
}

Everything was correct and now the recipe works fine without any changes.

don’t access to server event viewer, and key names are correct it’s just label
