[modeller_usage] align_codes error

I'm receiving the following error on linux with Modeller 9.2: _modeller.error: read_al_373E> Protein specified in ALIGN_CODES(i) was not found in the alignment file; ALIGN_CODES( 1) = mod2hg42

Here's the alignment line from my python file: aln = alignment(env, file='mod2hg42.fa', align_codes=('mod2hg42'))

Here's the contents of mod2hg42.fa (located in the same directory): >mod2hg42 EEKLRRYLKRTVTELDSVTARLREVEHRAGEPIAIVGXACRFPGDVDSPESFWEFVSGGGDAIAEAPADRGWEPD PDARLGGXLAAAGDFDAGFFGISPREALNXDPQQRIXLEISWEALERAGHDPVSLRGSATGVYTGSSTNDYGFLA VSDPDEAHPYAITGTASSVASGRVAYCLGLEGPAXTVDTACSSSLTALHLAXESLRRDECGLALAGGVNVLSTPM VTLGFDSQGGLAADGRIKPFSKAADGYTRSEGAGVLVLQRLSAARREGRPVLAVLRGSAVNQDGASNGLIAPSGP AQQRVIRRALENAGVRAGDVDYVEAHGTGTRLGDPIEVHALLSTYGAERDPDDPLWIGAVKTNVGHLESAAGVAG VXKAVLALRHGEXPRTLHFDEPSPQIEWAVSVVSQARSWPAGERPRRAGVSSFGFGGTNAHVIVEEAPEADEPV

I've tried dozens of combinations, but I can't get around this error. Any advice?
