Expression.Error 枚举中没有足够的元素来完成操作。电量查询

Question

以下是来自 power query (Excel 2016) 的股票代码的 m 代码。如果我输入正确的股票代码（如 MSFT），它会完美运行，但如果我输入不正确的股票代码（如 ddddddd），我会收到以下错误，“[Expression.Error] 枚举中没有足够的元素来完成操作。” 如何绕过此错误并为值输入 0？我能以某种方式使用 Try Otherwise 吗？

提前致谢！

(InputTicker as text) as table =>

let

Source = Web.Page(Web.Contents("https://finance.yahoo.com/quote/"&InputTicker&"/key-statistics?p="&InputTicker)),
    Data3 = Source{3}[Data],

#"Demoted Headers" = Table.DemoteHeaders(Data3),

#"Filtered Rows" = Table.SelectRows(#"Demoted Headers", each Text.Contains([Column1], "Forward Annual Dividend Yield"))
in

#"Filtered Rows"

Answer 1

尝试

 Data3 = try Source{3}[Data] otherwise #table({"First Column", "Second Column"}, {{"Forward Annual Dividend Yield",0}}),
