yeah, though from the evidence we're seeing here, it'd be nice to confirm this, because it seems as if it might not be.

[quote userid="189470" url="~/discussions/f/rules/28911/a-null-parameter-has-been-passed-for-month-function/114027#114027"] "asDate" is Date types[/quote]

Yes, but she mentioned it is of type Date only.

[quote userid="78077" url="~/discussions/f/rules/28911/a-null-parameter-has-been-passed-for-month-function/114026#114026"]What is in ri!taskProductionList? [/quote]

Namely, we need to verify that the "asDate" property of that rule input actually contains Date data. The month() function (afaik) typecasts its input as date, so for example if OP is trying to call this function on String data, it'll still return the same error message as seen here.

So "asDate" is a field which is in "taskProductionList".table.

moulikadas — Fri, 09 Jun 2023 17:46:08 GMT

Ikr, I was just showing how to do null handling and as far as compatibility concern, I assumed it was just a primitive type (date field), so will not disappoint but it seems like top level of null handling is also not applicable to this data. moulikadas can you please share the data you are using in items?

same error occurred yet

RE: A null parameter has been passed for month function

moulikadas — Fri, 09 Jun 2023 17:26:14 GMT

if(
a!isnullOrEmpty(index(fv!item, "asDate", null)),
false,
contains(
tointeger(local!month),
month(index(fv!item, "asDate", null))
)
)

I already used that one, but it's not resolved, bcz same error occurred. plz suggest another way

Please don't use isnull(). It was never a safe option. Instead, go for a!isnullorempty() should cover more usecases.

a!forEach(
  local!items,
  if(
    a!isnullOrEmpty(index(fv!item, "asDate", null)),
    false,
    contains(
      tointeger(local!month),
      month(index(fv!item, "asDate", null))
    )
  )
)

For instance the above. I added some additional checks since I don't know your data.

moulikadas — Fri, 09 Jun 2023 14:45:00 GMT

So how to write that?

RE: A null parameter has been passed for month function

laurensw — Fri, 09 Jun 2023 14:42:57 GMT

Always make sure to make expressions null-safe. i.e. don't process any value that you know already is null.

For the rest the error given is rather clear.

This the error

RE: A null parameter has been passed for month function

sanchitg0002 — Fri, 09 Jun 2023 14:40:11 GMT

Are you sure that the error is due to month() only? Can you post screenshot of the error?

RE: A null parameter has been passed for month function

moulikadas — Fri, 09 Jun 2023 14:35:29 GMT

No, it's not working. same error also showing

You need to first check that the date you are passing in month() is not null, add an if condition to it.

if(
  isnull(fv!item.asDate),
  false,
  month(fv!item.asDate) = local!month
)
