Internal Error when running twice as provider hook from alias

[Alberdi]

I've got a project where I want to automatically format the code when compiling, so I've added erlfmt as a provider hook. I didn't have any issues with this flow until I added an alias that runs ct and cover. In that case I always get an "Internal Error".

I can provide a minimal example that displays the bug:

ᐅ rebar3 -v 
rebar 3.17.0 on Erlang/OTP 23 Erts 11.2.2.2

ᐅ rebar3 new lib erlfmt_bug

ᐅ cd erlfmt_bug

ᐅ echo '

{erlfmt, [write]}.

{provider_hooks, [
    {pre, [{compile, fmt}]}
]}.

{alias, [
    {test, [
        {ct, "--cover"},
        {cover, "-m 100"}
    ]}
