@qkyy521314 Hello there! I'm here to help you with bugs, questions, or becoming a contributor. Just waiting for a human maintainer to assist you.

I found a similar issue related to a 400 error when trying to install a model supplier in Dify version 1.0.0 on a self-hosted Docker setup. The suggested solution involves the following steps:

Download the .difypkg file of the desired plugin from the Dify marketplace.
In the Dify web interface, use the local file installation option.
Upload the downloaded .difypkg file.
Wait for the installation to complete, as it may take some time.
If the plugin doesn't appear in the installed plugins list, check the Docker container logs using docker logs container_name and try reinstalling if the logs show successful installation ^[1].

Additionally, ensure that your proxy settings are correctly configured, as proxy issues can also lead to connection errors ^[2].

Error content { "code": "invalid_param", "message": "Reached maximum retries (3) for URL https://marketplace.dify.ai/api/v1/plugins/download?unique_identifier=langgenius/ollama:0.0.3@9ded90ac00e8510119a24be7396ba77191c9610d5e1e29f59d68fa1229822fc7", "status": 400 }

The actual marketplace URL path has been changed, but it cannot be configured

The error message indicates that the maximum retries for downloading a plugin from the marketplace URL have been reached, resulting in a 400 error. This could be due to an incorrect marketplace URL configuration. To address this, ensure that the environment variables NEXT_PUBLIC_MARKETPLACE_API_PREFIX and NEXT_PUBLIC_MARKETPLACE_URL_PREFIX are correctly set. If these are not set, the application will attempt to retrieve the values from the HTML document's body attributes data-marketplace-api-prefix and data-marketplace-url-prefix. If neither is available, the default values will be empty strings, which might cause issues ^[1].

Regarding the logs, the repeated "NameResolutionError" suggests a DNS resolution issue within your Docker environment. This could be causing the failure to resolve the marketplace URL. You might want to check your Docker DNS settings or ensure that your Docker containers have access to the internet for proper DNS resolution.
