Analysis of the NapCat Log:

The NapCat log shows a clear ENOENT error, which stands for "Error: No such file or directory." This error occurs during the copyfile operation, indicating that the file /root/TRSS_AllBot/TRSS-Yunzai/data/rcmp4/784848738/temp.mp4 could not be found when NapCat tried to copy it to /app/.config/QQ/NapCat/temp/73289a06-6036-4ad9-b023-a8bc53a5dac5.mp4.

This suggests a file access or path resolution issue within the Docker container setup. The path /root/TRSS_AllBot/TRSS-Yunzai/data/rcmp4/784848738/temp.mp4 is likely a location within the TRSS-Yunzai container, but NapCat, running in a separate container, cannot directly access it. Understanding the directory structure and how containers interact is crucial here. We need to figure out how to make the video file accessible to NapCat.

The error originates from the OneBotMsgApi.handleOb11FileLikeMessage function, which is responsible for handling file-like messages in the OneBot protocol. This means the issue arises when NapCat processes a message containing a file (in this case, a video). Tracing the flow from this function can help pinpoint exactly where the file access fails.

Analysis of the OneBot Client Log:

The OneBot client log echoes the same ENOENT error, further confirming that the file /root/TRSS_AllBot/TRSS-Yunzai/data/rcmp4/784848738/temp.mp4 cannot be accessed. This log provides additional context by showing the message parameters, including the file path and the group_id. It also highlights the send_msg action, indicating that the issue occurs during the message sending process.

The stack trace in the log points to the OneBotv11Adapter.sendMsg function, which is responsible for sending messages via the OneBot v11 protocol. This confirms that the error happens at the interface between TRSS-Yunzai and NapCat. The client is trying to send the video, but the file cannot be accessed during the process. This narrows down the problem to how the file path is being handled between the two containers.

Potential Causes and Solutions

Based on the error logs, the primary issue appears to be a file access problem between the Docker containers. Here are some potential causes and solutions to consider:

1. File Path Mismatch:

   • Cause: The file path /root/TRSS_AllBot/TRSS-Yunzai/data/rcmp4/784848738/temp.mp4 is specific to the TRSS-Yunzai container and not directly accessible from the NapCat container. Each Docker container has its own file system, and paths are relative to the container's root.
   • Solution: Implement a shared volume or a method to transfer the file between containers. A shared volume allows both containers to access the same files, while a file transfer mechanism (like an API endpoint or a dedicated service) can move the file from one container to another. This ensures that NapCat can access the video file.

2. Permissions Issue:

   • Cause: Even if the file path is correct, NapCat might not have the necessary permissions to read the file. Docker containers run with specific user permissions, and file access is subject to these permissions.
   • Solution: Ensure that the user running NapCat has read permissions for the video file. This might involve adjusting file permissions within the TRSS-Yunzai container or using Docker's user namespace remapping features to align user IDs between containers.

3. Incorrect File Handling in OneBot Adapter:

   • Cause: The OneBot adapter might not be correctly handling file paths when running in a containerized environment. It might be assuming a local file system structure that doesn't apply when containers are involved.
   • Solution: Review the OneBot adapter's code to ensure it correctly handles file paths in a containerized setup. This might involve adjusting how file paths are constructed or using environment variables to configure file storage locations. Debugging the adapter's file handling logic is crucial.

4. Missing Dependencies:

   • Cause: NapCat might be missing dependencies required to handle file operations, such as libraries for file copying or network communication. If a dependency is missing, NapCat might fail to copy the file to its temporary directory.
   • Solution: Ensure that all necessary dependencies are installed in the NapCat container. Check NapCat's documentation for a list of required dependencies and verify that they are present. Adding any missing dependencies can resolve this issue.

Debugging Steps

To further diagnose the issue, consider these debugging steps:

1. Verify File Existence:

   • Action: Shell into the TRSS-Yunzai container and verify that the video file exists at the specified path (/root/TRSS_AllBot/TRSS-Yunzai/data/rcmp4/784848738/temp.mp4).
   • Rationale: This confirms that the file is indeed present in the container where it is expected. If the file is missing, the problem lies in the file generation or storage process within TRSS-Yunzai.

2. Check File Permissions:

   • Action: Check the file permissions of the video file within the TRSS-Yunzai container. Ensure that the user running NapCat (or a group the user belongs to) has read access.
   • Rationale: This ensures that NapCat has the necessary rights to access the file. If permissions are incorrect, NapCat will not be able to read the file, even if it can locate it.

3. Test File Copying Manually:

   • Action: Try to manually copy the video file from the TRSS-Yunzai container to the NapCat container using docker cp or a similar command.
   • Rationale: This helps isolate whether the issue is specific to the NapCat application or a more general container-to-container file access problem. If manual copying fails, the issue likely lies in the Docker setup.

4. Inspect Docker Volumes:

   • Action: If using Docker volumes, verify that the volumes are correctly configured and mounted in both containers.
   • Rationale: Incorrectly configured volumes can lead to file access issues. Ensuring that volumes are properly set up is crucial for shared file access between containers.

5. Review NapCat and TRSS-Yunzai Configurations:

   • Action: Examine the configurations of both NapCat and TRSS-Yunzai to ensure they are correctly set up to work in a containerized environment.
   • Rationale: Configuration errors can lead to unexpected behavior. Reviewing the configurations helps identify any misconfigurations that might be causing the file access issues.
