Does REST API document integration supports word doc type

Summary:

We are currently utilizing REST APIs to create documents within OTM; however, we are encountering issues specifically when uploading .docx file types.

While the initial document creation step succeeds, the subsequent content upload triggers the following exception:

Error processing record: OTM file upload client error: 400 -
{
    "status": 400,
    "title": "Client validation error.",
    "detail": "HTTP 400 Bad Request",
    "o:errorDetails": [
        {
            "title": "GLExceptionProd"
        }
    ]

And here is the create document JSON payload with the documentMimeType,

Please let me know if you had encountered similar issue in uploading word documents and anything that I'm missing.

Thanks in advance!
