Steps to reproduce

Create empty workflow "Start" -> "LLM" -> "End"

Start part, use paste image link, input a presigned URL will report error

✔️ Expected Behavior

can accept the pre-signed URL

❌ Actual Behavior

Report error "URL does not exist"

To resolve the issue where the "Start" workflow in Dify version 0.6.14 does not support S3 pre-signed URLs and reports "URL does not exist," ensure that the S3 storage configuration is correctly set up in your .env file. Here is the relevant section from the provided docker-compose.yaml:

# The S3 storage configurations, only available when STORAGE_TYPE is `s3`.
S3_ENDPOINT: 'https://xxx.r2.cloudflarestorage.com'
S3_BUCKET_NAME: 'difyai'
S3_ACCESS_KEY: 'ak-difyai'
S3_SECRET_KEY: 'sk-difyai'
S3_REGION: 'us-east-1'

Make sure to replace the placeholders with your actual S3 configuration details:

Set STORAGE_TYPE to s3.
Provide the correct S3_ENDPOINT, S3_BUCKET_NAME, S3_ACCESS_KEY, S3_SECRET_KEY, and S3_REGION.

If the issue persists, verify that the pre-signed URL is correctly generated and accessible. Ensure that the URL is not expired and that the permissions for the S3 bucket allow access to the file ^[1]^[2].
