The error occurs in minimap-color-highlight-view.coffee at line 79, where getScope calls scopeDescriptorForBufferPosition. The tokenized buffer is undefined, likely due to a missing or invalid buffer reference. Start by examining the view's initialization and how it accesses the editor buffer. Check if the buffer exists when markers are updated. Run the package in Atom's dev mode to reproduce the error and trace the undefined value.
