输入数据无效。请验证唯一约束 Strapi

Question

我试图在我的 Strapi 产品中添加产品数据，但有时会显示“输入数据无效。请验证唯一约束”错误。有人以前处理过这个吗？

我的控制台中有

{statusCode: 400, error: "Bad Request", message: "Invalid input data. Please verify unique constraints"}

。

Answer 1

由于软件包版本不匹配，这发生在我身上。对我有用的最终解决方案是将软件包升级到 3.5.x.

Answer 2

这发生在我身上，因为我的一些模型文件中缺少

const axios = require('axios');

。我自己为每个使用 axios 发送 POST 请求的模型做了 webhooks。

尝试

npm run strapi console

这非常有帮助。当我尝试更新单一类型的字段时，它确实在控制台中显示了一个包含足够信息的错误。

也许你在你的模型/服务/控制器中遗漏了一些东西。希望 Strapi 控制台会显示它。

如果这是在生命周期钩子的上下文中，我在 v3 中尝试做一个时遇到了这个错误。

我的错误是没有在 beforeUpdate 方法中添加另一个参数

Before : 
async beforeUpdate(data) {
  console.log(data);
  data.ImageUrlTest = "testurlimage";
},


After:
async beforeUpdate(params, data) {
  console.log(params);
  data.ImageUrlTest = "testurlimage";
},

我今天遇到了同样的问题。前端显示的“输入数据无效。请验证唯一约束”似乎是一条包罗万象的消息，并不总是表示存在唯一约束问题。

就我而言，这是因为我试图在特定字段中输入的值比字段的最大长度长。 我们为该字段选择了数据类型

Short text

，但发生错误时我试图保存的特定值是 283 个字符长。

您可能会发现您的问题是类似的数据库错误，也被通用错误消息掩盖了。

我能够通过阅读 Strapi 服务器日志找到这个错误——这揭示了实际的错误消息
