[BUG] Don' report error on non-string scalar types

[staabm]

Bug Description

Parameter $isOAuth .. might contain sensitive information

is reported for non-string arguments like bool, float, int - which IMO does not make sense.

would be great the error would only be reported for string, array (which might contain strings), or object (which might contain string properties)
