fun getErrorList() =
compareAddress(loanData.loan.propertyAddress,payload.propertyAddress)
fun compareAddress(loanpropertyAddress, inputPropertyAddress) =
if(null != loanpropertyAddress and null != inputPropertyAddress)
getAddr1 (loanpropertyAddress splitBy(" "))[0]
==

The problem is how you are calling the getAddr1 function. In the DataWeave expression you provided, your passing to the getAddr1 function an array of strings instead of a string:

...
getAddr1(
    loadpropertyAddress splitBy(" ") // splitBy returns an array of strings
)[0] // here, you're trying to get the first element of the value returned by getAddr1
...

I'm assuming you are trying to compare the first part of loan and input property addresses after removing "#" characters. If my understanding is correct, then you can do the following changes to your function:

...
getAddr1(
    loadpropertyAddress splitBy(" ")[0] // get the first element of the string array returned by the splitBy function
) // removed array item selector ([0])
...

With that modification, your DataWeave expression should look like:

fun getErrorList() =
compareAddress(loanData.loan.propertyAddress,payload.propertyAddress)
fun compareAddress(loanpropertyAddress, inputPropertyAddress) =
if(null != loanpropertyAddress and null != inputPropertyAddress)
getAddr1 (loanpropertyAddress splitBy(" ")[0])
==
getAddr1 (inputPropertyAddress splitBy(" ")[0])
else
null

fun getAddr1(addr1) =
addr1 replace "#" with ("")
