Bug: Null reference error when pasting attachments on canvas

[ProjectLiminality]

Bug Report: Null reference error when pasting attachments on canvas

Summary: A null pointer exception occurs in the CustomAttachmentLocation handler when attempting to paste content while editing text on a DreamSong canvas, causing the paste operation to fail. This happens because the code attempts to read the 'basename' property from a null object.

Category: Bug

Estimated Complexity: Moderate

Error:
Cannot read properties of null (reading 'basename')

Error ID: IB-ERR-ced30d89

Additional Report

AI Analysis: This occurrence confirms the original null reference bug but adds specificity about the trigger mechanism—pasting entire sentences into canvas text elements appears to be the reliable reproduction path. The Apple Silicon macOS environment matches previous reports, suggesting the issue isn't platform-specific. The consistent trigger (sentence pasting) strengthens confidence in reproducibility and points toward a parsing or object initialization failure when handling multi-word text input on canvas elements. This data supports prioritizing a fix around text validation or basename property assignment during paste operations.

User Description:
It seems to stem from pasting entire sentences into the text elements on the canvas

Environment:

• InterBrain: v0.9.0
• Obsidian: v1.8.10
• Platform: macOS (10.15.7 (Apple Silicon))
