使用向导生成Odoo11自定义报告.格式错误:不是PDF或已损坏

Question

我正在尝试基于向导打印Odoo自定义报告。它接受来自向导视图的输入。该向导允许用户选择具有start_date和end_date的项目。然后单击打印按钮。因此与向导表单字段过滤器匹配的活动列表应该打印在CCD_ 1中。但我得到了一个带有0 KB的PDF文件，当我尝试打开时，我得到了Format error: Not a PDF or corrupted.，控制台中没有错误以下是一些关键文件

docs = self.env['ew.pta.line'].browse(docids)

docargs = {
"doc_ids": docs.ids,
"doc_model": "ew.pta.line",
"docs": docs,
}
return docargs

尝试通过"report_action"调用删除您的"data"参数。自身已包含数据。
