Hello @Alleyway-boop! I'm here to assist you with bugs, questions, and contributions. Let's get this issue sorted out together!

To resolve the "Invalid file input error" when trying to regenerate a conversation with an uploaded picture in Dify version 1.0.0 on the cloud, ensure that you have enabled the "Image Upload" feature correctly. For Chatflow applications, you should:

1. Enable "File Upload" in the features and select only the "image" file type.
2. Enable the Vision feature in the LLM node and specify the sys.files variable.

If these steps are not correctly followed, it might lead to errors such as "Invalid file input error". Make sure these configurations are set properly and republish the application if necessary ^[1].
