REST API ignores values from Binding

[Num4mer]

Hey everyone,

i'am facing a problem that my POST calls to an REST API ignoring the content of the defined binding.

What i will do is sending a userShortCut to the API and get back the userName, as example MM -> Magic Meercat.
The userShortCut will be filled in the frontend by the user and shall to be handed over with a binding userShort.

Now the problem is very similar to #10946 but i can't delete the "Binding." as descriped in the solution of the post.
Every time i delete the "Binding." it is not possible to save the change.
If some more changes are done and it is possible to save, the "Binding." is there again after switching between data and design window.

the body is:

the binding looks like:

action in frontend:

request body in action:

I'm a bit confused because in the request body of the action the "Binding." is not available.

If i fill in a default value in the REST API everything works fine.
It doesn't make any difference if i fill in values in the binding field of the "Execute Query" as default or load a value from a text field.

Is there anybody how can helb me?

Best regards.

Hey @Num4mer

In your Query, don't use the prefix "Bindings".

An example query that I have set up to create a record in MongoDB looks like this:

To edit your query, you'll need to do so from the Data tab (not from the Execute Query action step. You should also then run the query successfully, and save it. Switching to the Design section and the Execute Query action step should then reflect the changes you've made.

@mikesealey i hope my explanation is clear?

When you send the request, what are the results?

[Num4mer]

1. with filled in default value in the Data tab:
   

2. without default value in Data tab

3. this is the button action
   

everything filled in under {{Benutzer.Fields.Benutzerkuerzel }} -> will make a result as in 2.
so it looks to me like the binding between design and data tab is not working

There are a couple of things happening here:

Firstly, you should set a default value to fall back on.
Any time you make a change, you must send a request that returns data in order to save it
You don't need to use {{ Binding.userShort }} simply {{ userShort }} - you should make this change in the data tab, send a successful request that returns data, and save it.
You can then use the query from the Design tab.

this workaround does not work because:

1. i go to Data tab
2. -> tab Bindings, add the default value
3. switch to tab Body
4. i change the Body -> delete the "Binding."
5. send a request and get positiv return data for default Value
6. i save it
7. i got a positiv saving sucessful
8. i switch to the design tab and back to data tab
9. now there ist writen "Binding.userShort" again

every time i delete "Binding." in the body of the request (data tab) the system will add it again

if i try to do only the points 3-5 it is not possible to click save because it is not clickable

i am totally confused about the behavior of the system
