Link to index page with getServerSideProps and basePath results in full page reload

[bernardop]

Bug report

Describe the bug

Using the experimental basePath and linking from any page back to the index page with Link results in a full page reload if the index page uses getServerSideProps. Looking at the network tab in Chrome I see a request to http://localhost:3000/base/_next/data/development.json that 404s. In the production build, the request that 404s looks like this http://localhost:3000/base/_next/data/xpCmLw_g1hPw_3b847mWF.json. I believe there's a / missing before .json.

To Reproduce

1. Clone this repo https://github.com/bernardop/next-basepath-repro
2. Install dependencies and yarn dev
3. Go to http://localhost:3000/base
4. Click on "a" or "b"
5. Click on "Back" link
6. Index page does a full load and the network tab shows 404 to .json

Expected behavior

Index page should not fully reload.

System information

• OS: macOS
• All browsers
• Version of Next.js: 9.4.5-canary.8
• Version of Node.js: 14.4.0

Additional context

I believe this was introduced in 9.4.5-canary.8 and I suspect #13876 is the culprit. 9.4.5-canary.7 does not have this error.

Hi, this should have been resolved in v9.4.5-canary.14 of Next.js specifically this PR #14376

Closing as this is resolved on latest canary, please reply with additional details if you are still encountering problems after upgrading

Thanks @ijjk, just confirmed it works perfectly now. Also great to see basePath out of "experimental"!

Also confirming this issue seems to be fixed in latest canary 👍 looking forward to 9.4.5!
