为什么会有无效参数?发生这个错误是因为一个参数文件是无效的或不被接受的。参数是指在文件中的某一列（特指列的标题）。该错误意味着列标题中可能包含不可接受的符号或映射出现问题。

如何解决这个问题：检查并确保您的表格包含所有必需属性列，且列标题与Wish的模板匹配或相近(例如，‘’库存‘’的‘’数量‘’是正确的)。

此外，这也可能是映射问题。映射是让您表格中的列标题与Wish的进行匹配。如果您上传的文件中列的标题与我们的略有不同，您在上传之前将会被提示将他们进行‘’匹配‘’。在以下示例中，相同列的标题和Wish的字段名称将自动映射。其他类似''Item SKU''(以下粉红色框)和"Unique ID"必须是匹配的。点击空白处将会出现下拉菜单，您可以从菜单中选择与之匹配的列标题。

当您完成映射后，‘’点击提交‘’按钮将会变成蓝色，点击这个按钮，表格即可开始上传。确保您已将所有的字段与Wish字段进行匹配，否则你将会收到“操作失误”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.
