Trying to delete an alias from a image, but got error "500 Internal Server Error".

Using uptrace and here's the log message:

getting 401 when trying to access backend API GET /api/aliases right after start up of docker compose, but after 1 ~ 2 minutes, it's ok.

I suspect it's the race condition happening at App.tsx (conflicts between "login" and "fetch aliases"). Please investigate the possible issue.

When I tried to delete an alias from a image, I got err "500 Internal Server Error". Log message:

:8080/api/image/2/aliases:1 
 Failed to load resource: the server responded with a status of 500 (Internal Server Error)
api.ts:114 
 PUT http://localhost:8080/api/image/2/aliases 500 (Internal Server Error)
updateImageAliases	@	api.ts:114
handleSaveImage	@	App.tsx:101
handleSave	@	ImageModal.tsx:48

When an image is deleted, the alias entries at side barand buttons "previous page" and "next page" at top & bottom of main region of webpage are not updated synchronously.

The aliases handling mechanism seems to have some bugs: I test with single image huh.png, added 16 testing aliases: ["huh", "what", "huh2", "huh3", 4, 5, 6, 7, 8, 9, 0, 1, 2, 3].

The side bar's numbering at page 1 isn't correct, it should be #1, #2, #3, #4, #5, but it's #1, #3, #5, #6, #7. Page 2, 3 are correct.
There are more than 5 alias rows at the main region of webpage, and the alias string at each row is wrong.
- Page 1: 4, huh2, huh3, Alias #8, Alias #9, Alias #10, Alias #11, Alias #12, Alias #13, Alias #14, Alias #15, Alias #16
- Page 2: 5, 6, 7, 8, 9, Alias #5, Alias #6, Alias #7, Alias #13, Alias #14, Alias #15, Alias #16
- Page 3: 0, 1, 2, 3, Alias #5, Alias #6, Alias #7, Alias #8, Alias #9, Alias #10, Alias #11, Alias #12 It seems I didn't modify the pagination mechanism correctly (originally you implemented 5 aliases per page, but I want it to be 10 aliases per page).

It seems there is a permission issue when backend tried to run make swagger.

I correctly access the backend API with the cookie provided by backend, but why do I still see this error: Failed to load resource: the server responded with a status of 401 (Unauthorized) (Login and seeing webpage is ok, but can't fetch aliases)
