1. Perform Odata API Upsert/Insert Operation using SFOdata.Attachment entity
2. See error when upserting/insert xx.docx, xx.doc file or fileContent string.

When a non MS Word document type was in fact not converted to base64 string.
If the fileName is xxx.doc or xxx.docx, but the file content is not a MS Word document, the Insert/Upsert/Update operation of API will not succeed.

Examples of occurence: a string or text file was instead converted to base64; an RTF file was renamed as .doc/.docx extension, etc.

Ensure that the data in 'fileContent' field of the request payload is a valid base64 encoded string of a xx.doc or xx.docx file. (You may use the instructions in resolution of KBA 2940547 to check that)
