[Feature Request] Ignore file not exists error when deleting files from KB

[konokenj]

Describe the solution you'd like

When trying to delete a file from a newly created knowledge base in the web UI, it can be updated without an error even if the file cannot be found.

Why the solution needed

Let's say we've created a new knowledge base from the web UI and uploaded a file. The file will be uploaded to the S3 bucket, but there is a possibility that the user will later delete it from the bucket.
Currently, if a file is not found, the The file does not exist in bucket. error occurs, and the bot cannot be updated. To avoid this to update the bot, users will need to change the table or restore the file to the S3 bucket.

Additional context

Even if the file cannot be found in the S3 bucket, there are no side effects of skipping the deletion and finishing normally. Currently, this error is only shown in the developer tool log, and nothing is displayed on the screen.
