Based on your description, I think this is the line causing an error.
bcrypt.checkpw(lcase(password),Member.getMemberPassword())
I might just add some more granular logging before the statement that would
maybe nail down what is amiss.
try { writeoutput(lcase(password)); } catch (any e) { write error 1 }
try { writeoutput(Member.getMemberPassword()); } catch (any e) { write
error 2 }
try { writeoutput(bcrypt.checkpw('test','test')); } catch (any e) { write
error 3 }
try { writeoutput(bcrypt.checkpw(lcase(password),Member.
getMemberPassword())); } catch (any e) { write error 4 }
bcrypt.checkpw(lcase(password),Member.getMemberPassword())
Could maybe also pull out the checkpw function from inside the if an set to
a variable.
var chkResult = bcrypt.checkpw(lcase(password),Member.getMemberPassword())
if(isDefined("chkResult") and !isNull(chkResult) and isBoolean(chkResult)
and chkResult){.....
if statement might be a bit overkill, but may handle the error more
gracefully.
