LEDES Error: BF103 Invalid Mime Type

Overview of the Issue

The error message:
BF103 - "Invalid MIME type."

This error occurs when the file you're attempting to upload has an unsupported or incorrect MIME type. The system only accepts specific MIME types for files, and an invalid type will result in this error.

Allowed MIME Types:

• application/msword
• application/pdf
• application/vnd.ms-excel
• application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
• application/vnd.openxmlformats-officedocument.wordprocessingml.document
• image/jpeg
• image/png
• image/jpg
• text/plain
• text/xml
• application/xml
• application/vnd.ms-outlook
• application/vnd.openxmlformats-officedocument.presentationml.presentation
• image/tiff
• application/vnd.ms-powerpoint
• message/rfc822

If the file you are uploading does not match one of these allowed MIME types, the system will reject it.

Troubleshooting the Issue

Step 1: Verify the File’s MIME Type

• Ensure that the file’s MIME type matches one of the allowed types listed above.
• Files with formats like HTML, XML, or other unsupported MIME types will trigger this error.

Tip: Use a tool or inspect your file properties to verify its MIME type. You can also open the file in its respective program (e.g., Word, Excel) to ensure it matches one of the accepted formats.

How to Fix

Step 1: Convert the File to an Allowed MIME Type

• If the file’s MIME type is not listed, convert it to a supported format such as PDF, Excel, or Word.
• Ensure that your file format aligns with one of the allowed types.

Step 2: Re-upload the Corrected File

• After converting the file to the correct MIME type, re-upload the file to the system.
