Failed to parse field country in row 1: Cannot read properties of undefined (reading 'repository')

I’m new to Nocobase and tried to import some data with the Excel template provided by Nocobase. I always got the error “Failed to parse field country in row 1: Cannot read properties of undefined (reading 'repository')”.
I suppose that I should not input the “United States” in the Country field directly. Could anyone please help to guide me? Thanks.

Please reproduce this problem in the demo environment.

在demo上创建都正常,自己创建的就有这个问题好奇怪。

在数据表里创建多对一字段,然后删除几次,在后在现在导入数据这个功能,导入execl表填写新增字段数据就会报错。
