针对AI知识库，采用的是通过接口的方式将文档导入知识库，类似于这样：
app.rags.integratedManagementOfTheKnowled.addDocumentByBusinessId(‘aa’, [{ “fileName”: ‘aa’, “size”: size, “url”: ‘https://wd.hbxtxzl.cn/group1/M00/02/3E/CsiNamj4RdmAdH19ABkvYlzOmJY995.pdf’, “type”: ‘’}], {“chunkSeparator”: [“\n”], “chunkSize”: 1024, “chunkOverlap”: 100}, {“chunkCleaning”: True})
最近发现，有些文档通过这种方式导入后，知识库内并没有显示该文档
所以我采取了将文档下载到本地导进去的方式：
会出现向量化失败的情况：
错误信息如下：

因此想请问一下，这是什么原因造成的，如何解决并修复
