@hexxyan Hello! I'm here to help you with any bugs, questions, or contributions you have. Let's tackle this issue together!

In Dify, once a chunk mode is selected and the knowledge base is created, it cannot be changed later. This is a limitation of the Chunk Settings feature. Any new documents added will follow the same chunking strategy that was initially set ^[1].

Hi,

I've faced the same issue; on Chunk Settings page for the existing documents, we cannot update Delimiter or Maximum chunk length as the Save & Process button has been disabled.

This is due to the condition !datasetId:

dify/web/app/components/datasets/create/step-two/index.tsx

Line 1004 in bc3a570

{!datasetId && <Button loading={isCreating} variant='primary' onClick={createHandle}>{t('datasetCreation.stepTwo.save')}</Button>}

This line is updated by your commit: 9214cc8#diff-9a598b3479094455005fb30da13e5a1065aa5a3f8a3b007ccec7b38993dad7dfL1013 in #12206

In the current implementation, StepTwo can never be called without datasetId, so there is no chance for the Save button to be displayed on the Chunk Settings page for existing documents.
Is there any specific reason why this button is disabled on the Settings page? Is this intended or bug?

Thanks in advance!
