Julia代码出现DimensionMismatch维度不匹配错误求助

我正在开发一段代码，以下相关代码执行时出现维度不匹配错误：

# path_skaters 是指向球员信息csv文件的路径（参考示例文件格式）
path_skaters = "https://raw.githubusercontent.com/dscotthunter/Fantasy-Hockey-IP-Code/master/example_skaters.csv"

# path_goalies 是指向守门员信息csv文件的路径（参考示例文件格式）
path_goalies = "https://raw.githubusercontent.com/dscotthunter/Fantasy-Hockey-IP-Code/673b0a5119ed746a8dc2347206d138c84407def1/example_goalies.csv"


goalies = DataFrame(CSV.File(HTTP.get(path_goalies).body, normalizenames=true, delim=","))

skaters = DataFrame(CSV.File(HTTP.get(path_skaters).body, normalizenames=true, delim=","))


the_lineup= formulation(skaters, goalies, hcat(zeros(Int, num_skaters + num_goalies), zeros(Int, num_skaters + num_goalies)), num_overlap, num_skaters, num_goalies, centers, wingers, defenders, num_teams, skaters_teams, goalie_opponents, team_lines, num_lines, P1_info)
the_lineup2 = formulation(skaters, goalies, hcat(the_lineup, zeros(Int, num_skaters + num_goalies)), num_overlap, num_skaters, num_goalies, centers, wingers, defenders, num_teams, skaters_teams, goalie_opponents, team_lines, num_lines, P1_info)
tracer = hcat(the_lineup, the_lineup2)
for i=1:(num_lineups-2)
    try
        thelineup=formulation(skaters, goalies, tracer, num_overlap, num_skaters, num_goalies, centers, wingers, defenders, num_teams, skaters_teams, goalie_opponents, team_lines, num_lines, P1_info)
        tracer = hcat(tracer,thelineup)
    catch
        break
    end
end

报错信息：

DimensionMismatch: mismatch in dimension 1 (expected 1 got 190)

我推测这个错误和球员+守门员数据框的总数量190有关，但没法明确具体问题所在，求解决思路。
