API responds `400` with `oh-input-card`

[ErikDB87]

The problem

I've got this page:

config:
  icon: water
  label: Irrigatie
  order: "7"
  sidebar: true
blocks:
  - component: oh-block
    config:

I tried updating Kranen_irrigatie_Power_2 via the oh-input-card, but:

Nothing is logged in the openHAB log, but that doesn't seem all too illogical, because this is logged in Chrome's log:

If I copy the HTTP request "as cURL (bash)", this is the output:

  --data-raw $'60 30\'00"' \

I'm also making a GitHub issue for this.

Expected behavior

I expect a 500 response.

Steps to reproduce

I suppose:

1. Create an oh-input-card component.
2. Try to change the state of an item.

What type has that Item?

[ErikDB87]

What type has that Item?

version: 1
items:
  Kranen_irrigatie_Power_2:
    type: Switch
    label: Druppelslang (16 mm)
    icon: Switch
    groups:
      - Kranen_irrigatie
    tags:
      - Power
      - Switch

[florian-h05]

You cannot send 60 30‘00 to a Switch Item, that’s no valid command, which causes the server to answer with 400 Bad Request because you make a invalid request.

Apologies, I meant this item:

version: 1
items:
  Kranen_irrigatie_AutoOFF_Timer_2:
    type: Number
    dimension: Time
    label: Druppelslang automatisch af
    icon: Time
    unit: s
    groups:
      - Kranen_irrigatie
    tags:
      - Duration
      - Setpoint
    metadata:
      stateDescription:
        value: ' '
        config:
          pattern: '%1$tM''%1$tS"'

[florian-h05]

Can you sent that command through the console?

openhab:send itemname command

Or through a rule?

[ErikDB87]

openhab:send itemname command

Or through a rule?

Yes.

[florian-h05]

And through the API explorer?

[ErikDB87]

And through the API explorer?

What's that?

[Nadahar]

What's that?

[ErikDB87]

And through the API explorer?

That works as well:

[florian-h05]

You cannot send 60 30'00" through oh-input and then test with a totally different value through the API, that's pretty pointless ...
The curl request you posted at the top says you attempted to send 60 30'00" as a command.

Why/How did you enter that value? This is no valid command to a Number:Time Item.

[ErikDB87]

Aha, I see what you mean:

--data-raw $'60 30\'00"' \

I assume that's where the problem lies?

This is how my page looks:

I just typed in the value 60. The value 100'00 is the current state, and isn't part of the input field. If I now click on the V-shaped check thingy, this happens:

And the payload is `60 100'00"`. (No idea why the back-tickes refuse to work here...?)

So somehow, the current (read-only) state is "sucked into" the payload.
