Error: Unexpected token when including a file with `declare namespace` in it.

Tái hiện lệnh được báo cáo, microbundle --jsx React.createElement --tsconfig tsconfig.build.json, bằng cách sử dụng tệp OpenSeadragonV5.d.ts được tham chiếu. Trước tiên, hãy kiểm tra tsconfig.build.json và .babelrc.json để xem các tệp khai báo và declare namespace được phân tích như thế nào. Được xem là hoàn thành khi package build thành công mà không có lỗi cú pháp Babel hoặc lỗi token không mong đợi.

Hi microbundle team.

I'm trying to build a package, and I've needed to override some types since the types repo for the main dependency hasn't been updated.
I was on 0.14.x before, but I updated to 0.15.1 and I still get this error.

$ microbundle --jsx React.createElement --tsconfig tsconfig.build.json
Error: Unexpected token (Note that you need plugins to import files that are not JavaScript)

at /Users/user/Documents/osd-react-renderer/packages/renderer/src/types/OpenSeadragonV5.d.ts:3:8

1: /* eslint-disable max-classes-per-file */
2: 
3: declare namespace OpenSeadragon {
           ^
4:     export function isFunction(obj: unknown): boolean;

I actually had two errors in this file. The first error said:

osd-react-renderer: (babel plugin) SyntaxError: /Users/user/Documents/osd-react-renderer/packages/renderer/src/types/OpenSeadragonV5.d.ts: Missing semicolon. (3:7)
osd-react-renderer:   1 | /* eslint-disable max-classes-per-file */
osd-react-renderer:   2 |
osd-react-renderer: > 3 | declare namespace OpenSeadragon {
osd-react-renderer:     |        ^
osd-react-renderer:   4 |     export function isFunction(obj: unknown): boolean;
osd-react-renderer:   5 |
osd-react-renderer:   6 |     export function isCanvasTainted(canvas: HTMLCanvasElement): boolean;
osd-react-renderer: at undefined:3:7

This error I was able to resolve with a .babelrc.json file, but I can't see what configuration can be used to resolve the first error.

I noticed that previously we were able to build the app when we used declare module OpenSeadragonV2, but declare namespace` specifically is causing this.

Any suggestions on what configuration can resolve this issue?

Thanks
