ARM账号注册报错The claims exchange 'Salesforce-UserWriteUsingEmail' specified in step '14' returned HTTP error response with Code 'BadRequest' and Reason 'Bad Request'.解决方案

为了下载一些文件，最近需要注册一个arm官网的账号。注册归注册，在登录时需要update profile。更新就更新呗，填一些却发生了报错：

The claims exchange 'Salesforce-UserWriteUsingEmail' specified in step '14' returned HTTP error response with Code 'BadRequest' and Reason 'Bad Request'.

在多次登录不成功后，报错又改变了：

Your account is almost set up, however, before you can use it, we need to review the details to comply with export regulations. This can take up to 5 working days. If after 5 working days you are not able to log in, let us know using onlinesupport@arm.com.

解决方案：profile中的每个表单项都要求至少3个字符。后台对此作了限制，但前端却没有，直接把不合法的数据提交了。呵呵，这个问题还是偶给arm客服发了n封邮件后才找到的原因。
