[BUG] Watch mode crashes with `TypeError: thisArg.isLocalTemplate is not a function`

[sahillllllllll-bit]

Describe the bug.

When running the CLI with --watch, the process crashes immediately after initial generation with:

TypeError: thisArg.isLocalTemplate is not a function

The error occurs inside runWatchMode() in:

cli/src/utils/generate/watcher.ts

The function incorrectly calls:

thisArg.isLocalTemplate(...)

However, isLocalTemplate is a standalone exported function, not a method on the CLI command instance (thisArg). This results in an undefined function call and crashes watch mode.

Expected behavior

When running CLI with --watch:

• Initial generation should complete successfully.
• Watcher should start monitoring changes.
• No runtime errors should occur.
• The process should remain alive and continue watching for changes.

Screenshots

How to Reproduce

1. Run watch mode:

 asyncapi generate fromTemplate asyncapi.yaml @asyncapi/html-template --watch --output ./out

2. Observe initial successful generation.

3. After watcher starts, the CLI crashes with:

   TypeError: thisArg.isLocalTemplate is not a function
