problem with regular expressions

[Dario-Rosa85]

I get an error message when my code include a regular expression.
Here an example:

input = "4457418557635128"
visa = r"^(?:4[0-9]{12}(?:[0-9]{3})?)$"
if occursin(visa, input)
println("credit card found")
m = match(visa, input)
println(m.match)
println(m.offset)
println(m.offsets)
end

I get this error message

: MethodError(convert, (Type, nothing), 0x0000000000006a26)

does anybody know how to fix it?

Please do not use the linter. Lint.jl is not working, and we have not found a way to integrate StaticLint.jl

julia-vscode/StaticLint.jl#14
julia-vscode/StaticLint.jl#37

I don't know how to use StaticLint. The documentation is missing

Fixed in #119
