API returned 400 (Invalid client)" Error in Spotify Integration

[EchoSingh]

I have encountered an issue with the Spotify integration where the following error message keeps showing up:

1 error(s) occurred
[
  {
    name: 'music',
    result: {
      error: {
        message: 'API returned 400 (Invalid client)',
        instance: {
          error: 'invalid_client',
          error_description: 'Invalid client'
        }
      },
      provider: 'Spotify',
      mode: 'Recently played'
    }
  }
]

This error happens when trying to retrieve recently played music from Spotify. I have tried searching for similar issues, but none seem to match this exact problem. Could anyone provide guidance or suggestions on how to resolve this?
