我在Android上遇到了同样的问题，我面临的问题是，我的amplifyconfiguration.json有额外的设置，用于托管UI，我没有使用。通过删除它们，我能够解决这个问题。最后，我的amplifyconfiguration.json看起来像这样:

{
"auth": {
"plugins": {
"awsCognitoAuthPlugin": {
"CognitoUserPool": {
"Default": {
"PoolId": "us-east-1_xxxxxxxx",
"AppClientId": "xxxxxxxxxxxxxxxx",
"Region": "us-east-1"
}
}
}
}
}
}

注意:我只使用用户池，而不是身份池，所以我可以从AWS文档中的默认json结构中删除更多内容。
