Sourcemaps are not being uploaded - nuxt.js

I’m trying to upload source maps so that there will be more details to errors. but upon trying to upload, I always get the release with version already exists

if I try to run
sentry-cli releases files 55df8c27e47eda07d357ce0c14b877e07807e65e upload ./dist/_nuxt/ '~/_nuxt/'

, I will get the error of
sentry reported an error: unknown error (http status: 413)

I’m using API_key for authorization with scopes:

project:read
member:read
project:write
event:read

Sentry version is on version 8.0.6

I’m still no where to being successful in uploading the sourcemaps.
