[GitHub] [echarts] liujiaang opened a new issue #15527: typeScript 下 echarts.registerMap，提示错误，怎么解决
liujiaang opened a new issue #15527:
URL: https://github.com/apache/echarts/issues/15527
### Version
5.1.2
### Steps to reproduce
import * as echarts from 'echarts/core';
import chinaMap from './china.json';
echarts.registerMap('china', chinaMap);
提示报错 类型“{ type: string; features: ({ type: string; properties: { id: string; size: string; name: string; cp: number[]; childNum: number; }; geometry: { type: string; coordinates: number[][][]; }; } | { type: string; properties: { ...; }; geometry: { ...; }; })[]; }”的参数不能赋给类型“MapInput | GeoJSONSourceInput”的参数。
不能将类型“{ type: string; features: ({ type: string; properties: { id: string; size: string; name: string; cp: number[]; childNum: number; }; geometry: { type: string; coordinates: number[][][]; }; } | { type: string; properties: { ...; }; geometry: { ...; }; })[]; }”分配给类型“GeoJSONCompressed”。
属性“type”的类型不兼容。
不能将类型“string”分配给类型“"FeatureCollection"”。
### What is expected?
怎么才能不报错
### What is actually happening?
希望知道引入什么类型会不报错

I think it's not a mistake of echarts.
According to the prompt, we can find the main problem is "The type "string" cannot be assigned to the type ""FeatureCollection""". After that we can jump to the type declaration in which file name called `shared.d.ts` whose path is `echarts/types/dist/shared.d.ts`
If you regist map by using GeoJSON, the type were limited by `GeoJSONFeatureCollection` `GeoJSONFeature` and `GeoJSONGeometry`.
Inspect the data in own code was inferred to be string by typescript, but echarts declare it as a literal "FeatureCollection".
**Solution:**
Add `as const` assertions to the field which were defined as literal. For example:
```json
{
type: 'FeatureCollection' as const,
features: [
{
id: '710000',
type: 'Feature' as const,
geometry: {
type: 'MultiPolygon' as const,
coordinates: [
......
],
encodeOffsets: [
......
],
},
properties: { cp: [121.509062, 25.044332], name: '', childNum: 6 },
},
]
}
```
@Ovilia Is my solution correct?

This issue is labeled with `difficulty: easy`.
@liujiaang Would you like to debug it by yourself? This is a quicker way to get your problem fixed. Or you may wait for the community to fix.
Please have a look at [How to debug ECharts](https://github.com/apache/echarts/blob/master/CONTRIBUTING.md#how-to-debug-echarts) if you'd like to give a try. 🤓

找一下对应的类型定义是哪里错了，然后提个 PR 吧
