Bug - E2002: wrong regex in Code

Blueprint name

Controller - IKEA E2001/E2002 STYRBAR Remote control

Home Assistant Core Version

Description

The variable last_controller_event is only filled if the helper_last_controller_event matches the regex "^{(("a": ".*"|"t": \d+.\d+)(,)?){2}}$". This requires that the "a" and "t" keys are separated by a comma AND a blank.
But the input_text is built as {"a":trigger_action,"t":as_timestamp(now())} with only a separating comma and no blank. Also after the colon a blank is expected which is not there. This means that the variable last_controller_event is never filled.
The correct code line should be:
last_controller_event: '{{ (states(helper_last_controller_event) | from_json).a

      if helper_last_controller_event is not none and (states(helper_last_controller_event)
      | regex_match("^\{((\"a\":\".*\"|\"t\":\d+\.\d+)(,)?){2}\}$")) else "" }}'

So (, ) is changed to (,) and the blank after the colon is removed.

I can confirm this bug.
Need to replace
regex_match("^\{((\"a\": \".*\"|\"t\": \d+\.\d+)(, )?){2}\}$")
to
regex_match("^\{((\"a\":\".*\"|\"t\":\d+\.\d+)(,)?){2}\}$")

I tested it on ikea_e1524_e1810.yaml
