Hi @Mina_Saad,
Welcome to the community 
Ensure to copy your n8n workflow and paste it in the code block, that is in between the pairs of triple backticks, which also could be achieved by clicking </> (preformatted text) in the editor and pasting in your workflow.
```
<your workflow>
```
Make sure that you’ve removed any sensitive information from your workflow and include dummy data or pinned data as much as you can!
There have been a few changes to the n8n Form Trigger node recently, and the new n8n Form Trigger node you inserted probably has a newer version of the node (v2.2) which doesn’t show the Using 'Respond to Webhook' Node" option but instead has the ‘Form Response’ option in the Options which does the same thing.
You can check the node version of a node by copying the node json into a text editor and looking at the typeVersion. You can also change the node version to the older one by editing the version number if you prefer the older one:
"nodes": [
{
"parameters": {...},
"name": "On form submission",
"type": "n8n-nodes-base.formTrigger",
"typeVersion": 2.2,
...What is it that you’re trying to do? Could you share a bit more details about your workflow and what you’re building?
Hello, I am in the same situation. @aya I am trying to get a file from the user, process it and then return the processed file to the user.
Hi @Dimitrie_David,
Welcome to the community
You can still choose to use the older version (v.2.1) by editing the typeVersion in the node json 
Or you can also copy the v.2.1 example below:
Hi Aya,
Thanks for your reply and clarification,
I am wondering why n8n took such a decision to remove this feature from the newer version, while it is a very good and useful feature, even Max has a nice template in using the form in building the Flux image generator.
Hey @Mina_Saad,
The option was removed because when using multi step forms we now assume you will be using the form ending option which has the ability to redirect a user or show a completion page.
We are aware that this does mean the node can no longer return a file, This is something we have a feature request open for to improve this option in the future.
