Error loading file Not a diagram file

The "Not a diagram file" error when uploading a file usually indicates that the uploaded file does not match the expected format or extension.

Possible causes and solutions:

• Incorrect file format: Ensure that the file is indeed a diagram in a supported format (e.g., .png, .jpg, .svg, .vsdx, etc.).
• Corrupted file: The file may be damaged or incomplete. Try opening it in another application.
• Incorrect extension: The file may have a diagram extension but contain a different type of data.
• Validation error on the system side: The system might be checking the file content by signatures or metadata. Make sure the file meets the requirements.

To resolve:

• Check the format and size requirements.
• Try saving the diagram again from the original editor.
• If the error persists, consult the documentation or system support for allowed formats.
