[BUG] Document Store [Save Config] button is not working as desired

[almirb]

Describe the bug
When clicking on [Save Config] button on the "Configure Embeddings, Vector Store and Record Manager" screen, doesn't save things.

To Reproduce

1. Go to 'Document Store' screen
2. Create new Document Store
3. Create a basic loader (can be Text File Document Loader) with some random text
4. Click on "Process".
5. Go to 'Upsert All Chunks' screen
6. Configure Embeddings, Vector Store and Record Manager data
7. Click on 'Save Config'
8. Go back to previous screen
9. Go to 'Upsert All Chunks' screen again

Expected behavior
Al the settings would be there, but the config screen is empty.

Setup

• Installation: docker
• Flowise Version: 2.2.7-patch.1.
• OS: Ubuntu 24.04
• Browser: Brave (but the API call was also tested with Insomnia)

Additional context

• I'm sure the browser is firing the /api/v1/document-store/vectorstore/save is being fired.
• The config is only written when using the 'Upsert' button.
• After the first 'Upsert', you can change something and 'Save Config'. The changes won't be there when returning to the screen.

One very weird thing that happened twice.....
After upserting the first Document Store, created another one.... went to the steps 1 to 9 above.... when return to 'Upsert All Chunks' I saw all the configs (embedding, vector store....) from my other Document Store! 😢 That makes no sense, but It happened twice.
