Value blank on error when ErrorMessage set in [PostProcessing]

[DrCoolHands]

The Problem

I have "ErrorMessage" set to "true" in my config.ini however I receive a blank value when there is an error.

The text in the config editor for "ErrorMessage" reads "Do not show error message in return value - in error case, the last valid number will be send out"

curl responce:

{
"default":
  {
    "value": "",
    "raw": "05807.25",
    "error": "Rate too high - Read: 5807.25 - Pre: 5607.27",
    "rate": "",
    "timestamp": "2022-11-03T13:24:03"
  }

I have tried setting "ErrorMessage" to "false" as well, and also receive a blank value on error.

Version

12.0.1

Expected Behavior

With ErrorMessage set to true, the last valid value is expected to be returned.

Screenshots

No response

Additional Context

PostProcessing section from config.ini

Might be a stupid qestion: But did you reboot the ESP after changing the ini file?

[DrCoolHands]

I rebooted after each change and confirmed the restart in the log file.
I have also fully power cycled the ESP with no change to the behaviour.

This is a misunderstanding of the Parameter ErrorMessage. This parameter is actually not used anymore, but will be removed.
In case of an detected error, the value will be empty and in the field error, there will be the information, what went wrong.

Thanks for the hint, I will remove this paramter soon.
