Bug report

Required System information

Strapi version: 4.21.0
Strapi plugin-i18n: 4.21.0

Describe the bug

When we creating a simple single type (with internationalization enabled) with simple text field (also with enabled localization for this field) and save it - it is saved for default locale only. When we switch to another locale and save it - it is not saved, as after page reload we cannot see the saved value.

1. Request made to save not default locale, looks like 200
   curl 'http://localhost:1337/content-manager/single-types/api::test-single-type-page.test-single-type-page/?locale=de'
   -X 'PUT'
   -H 'Accept: application/json'
   -H 'Accept-Language: uk-UA,uk;q=0.9,en-US;q=0.8,en;q=0.7,de;q=0.6,sq;q=0.5'
   -H 'Authorization: Bearer {secret}'
   -H 'Cache-Control: no-cache'
   -H 'Connection: keep-alive'
   -H 'Content-Type: application/json'
   -H 'Origin: http://localhost:1337'
   -H 'Pragma: no-cache'
   -H 'Referer: http://localhost:1337/admin/content-manager/single-types/api::test-single-type-page.test-single-type-page?plugins[i18n][locale]=de'
   -H 'Sec-Fetch-Dest: empty'
   -H 'Sec-Fetch-Mode: cors'
   -H 'Sec-Fetch-Site: same-origin'
   -H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/108.0.0.0 Safari/537.36'
   -H 'sec-ch-ua: "Not?A_Brand";v="8", "Chromium";v="108", "Google Chrome";v="108"'
   -H 'sec-ch-ua-mobile: ?0'
   -H 'sec-ch-ua-platform: "macOS"'
   --data-raw '{"localizations":[13,12,11,10,9,8,7,6,5,4,3,2,1],"Title":"qwe"}'
   --compressed
2. After reloading - it tries to get the data for the selected locale and have 404 status with NotFoundError
   curl 'http://localhost:1337/content-manager/single-types/api::test-single-type-page.test-single-type-page/?locale=de'
   -H 'Accept: application/json'
   -H 'Accept-Language: uk-UA,uk;q=0.9,en-US;q=0.8,en;q=0.7,de;q=0.6,sq;q=0.5'
   -H 'Authorization: Bearer {secret}'
   -H 'Cache-Control: no-cache'

   -H 'Pragma: no-cache'
   -H 'Referer: http://localhost:1337/admin/content-manager/single-types/api::test-single-type-page.test-single-type-page?plugins[i18n][locale]=de'
   -H 'Sec-Fetch-Dest: empty'
   -H 'Sec-Fetch-Mode: cors'

4. See error in console:

[raudinm]

I've been facing the same issue.

[thomsa]

Same here.

As I am saving any other local than the default, it constantly just overrides the default and does not save the other locale.

When trying to publish the secondary local, the admin says "Not Found".

I'll add my suspicion here:

Saving a Localization creates a new row:

I suppose something goes havoc here:

EDIT:

Found the issue, just looking for one more minute...

SELECT * FROM public.your_entity;

For some reason the locale info is not saved correctly, everything defaults.

Change the local here to your locale and it'll work.

@Eventyret I have edit the post

[antoine-bielawski]

I've tested multiple versions, Strapi 4.20.2 is the last one without this issue. The bug was probably introduced by this commit.

[nevosol]

Can confirm that issue is fixed in yesterday's release https://github.com/strapi/strapi/releases/tag/v4.22.0
