為什么會有無效參數?發生這個錯誤是因為一個參數文件是無效的或不被接受的。參數是指在文件中的某一列（特指列的標題）。該錯誤意味著列標題中可能包含不可接受的符號或映射出現問題。

如何解決這個問題：檢查并確保您的表格包含所有必需屬性列，且列標題與Wish的模板匹配或相近(例如，‘’庫存‘’的‘’數量‘’是正確的)。

此外，這也可能是映射問題。映射是讓您表格中的列標題與Wish的進行匹配。如果您上傳的文件中列的標題與我們的略有不同，您在上傳之前將會被提示將他們進行‘’匹配‘’。在以下示例中，相同列的標題和Wish的字段名稱將自動映射。其他類似''Item SKU''(以下粉紅色框)和"Unique ID"必須是匹配的。點擊空白處將會出現下拉菜單，您可以從菜單中選擇與之匹配的列標題。

當您完成映射后，‘’點擊提交‘’按鈕將會變成藍色，點擊這個按鈕，表格即可開始上傳。確保您已將所有的字段與Wish字段進行匹配，否則你將會收到“操作失誤”的提示。

Invalid Parameter

This error occurred because a parameter in the file feed is invalid or not accepted. A parameter is simply one of the columns (specifically the column title) in the feed. This could mean that the column title contains unacceptable symbols or it could also be a mapping issue.

Troubleshoot this issue: Check to make sure you have all the required columns and that the names of each column match or are close to the Wish Template (i.e. "Inventory" for "Quantity" is fine). 

Also, this could be a mapping issue. Mapping is just matching your column titles to 's. If you upload a feed file and your column titles are slightly different from ours, you are prompted to "map" them to ours before uploading. In the example below, the column titles that are identical to the Wish Field Name will map automatically. Others, like "Item Sku" (in pink rectangle below) for "Unique ID" must be mapped. Clicking on the space will reveal a drop-down menu with your feed file's column names to choose from.

Once you've mapped your columns, the "Submit Feed" button will light up in blue allowing you to proceed with the upload. Make sure you map all fields to the corresponding Wish field or you will get an error.
