hashcat 5.0.0 with Token length exception with sha1

[pmatos]

Hello

I was attempting (first time with hashcat) this:

Code:

$ echo "foo:$(echo bar | sha1sum | cut -d ' ' -f 1)" > test.txt
$ hashcat -m 100 -a 0 test.txt             
hashcat (v5.0.0) starting...

Hashfile 'test.txt' on line 1 (foo:e2...ffccdf271b7fbaf34ed72d089537b42f): Token length exception
No hashes loaded.

No idea why my hash wouldn't be a valid hash. Looks valid:

Code:

$ cat test.txt
foo:e242ed3bffccdf271b7fbaf34ed72d089537b42f

What's hashcat really complaining about here?
