Describe the bug
I get the following error trying to bundle my project containing @trpc/server 10.45.3:
Error: While trying to resolve module `@trpc/server/shared` from file `/Users/nbarnett/project/node_modules/@trpc/client/dist/index.mjs`, the package `/Users/nbarnett/project/node_modules/@trpc/server/shared/package.json` was successfully found. However, this package itself specifies a `main` module field that could not be resolved (`/Users/nbarnett/project/node_modules/@trpc/server/dist/shared.mjs`.
I note that the file @trpc/server/shared/package.json exists in 10.45.3 but did not exist in 10.45.2. The contents of this file is:
{"main":"../dist/shared.cjs","module":"../dist/shared.mjs","types":"../dist/shared.d.cts"}
However, none of these files exist, resulting in the observed error. The correct files are listed in the ./shared export in the top level package.json file, as they were in 10.45.2:
"./shared": {
"import": "./dist/shared/index.mjs",
"require": "./dist/shared/index.js",
"default": "./dist/shared/index.js"
}
Patching the package to remove this additional package.json file resolves the error.
