unknown tag <!lambda> when lambda used to return a value

[marcoaddario]

the !lambda syntax is not recognised when used to return a value

while it is recognized (and accepted) by the ESPHome integrated editor

The code is recognized as ESPHome (and not home assistant ;-) )

VSCode version: 1.75.1
ESPhome plugin version: v2022.11.0

Is anybody able to reproduce this?
I cannot:

Same issue here:

VSCode version: 1.76.0
ESPhome plugin version: v2022.11.0

Yes I'm getting this lambda unknown tag error in the yaml file in Home Assistant File Editor but not when editing from the ESPHome editor.

this is the code snippet
`binary_sensor:

• platform: gpio
  id: gpio21
  name: Water Sensor
  pin:
  number: 21
  mode:
  input: True
  pullup: False
  pulldown: True
  filters:
  • delayed_on: 30ms
    on_press:
    then:
    • switch.turn_on: gpio2
      - delay: !lambda "return id(glob_drain_delay) * 60000;"
    • switch.turn_off: gpio2
      `

this is the error message

`unknown tag !<!lambda> (78:64)

75 | ...
76 | ...
77 | ...
78 | ... id(glob_drain_delay) * 60000;"
-----------------------------------------^
79 | ...
80 | ...`

In VSCode I'm getting Unresolved tag: !lambda YAML
However, if using the ESPHome Validator in VSCode with the ESPHome Extension installed I don't get an error.

Do you have the redhat yaml extension installed? Try disabling it for the workspace

[mikesmitty]

If you want to keep the redhat yaml extension enabled you can add it as a custom tag in settings.json:

    "yaml.customTags": [
        "!lambda scalar"
    ]
