Hello 1nickt,

Support for hash ref was added recently. In your case, change the following line:

@{ get_data( $_ ) }

to this:

get_data( $_ )

[download]

Basically, give MCE the array ref directly so that it doesn't think to process the array containing a single hash ref as input_data => hash_ref behind the scene.

Regards, Mario

Update:

In the OP's case, the array contains nested hash elements. MCE can take an array ref \@array to ensure the data is processed as an array.

mce_loop {
    ...
} \@array;
