How should I use next-auth Line provider ?

[sktjgudals]

There is a client ID in my .env file, but it is not included in [get_authorization_url]
here is my debug console
[next-auth][debug][get_authorization_url] https://access.line.me/oauth2/v2.1/authorize?response_type=code&scope=profile%20openid&state=dc85deb1c09625c1f2652784ef31135546e12ae268eq79edb48w6559b61c3a8&redirect_uri=http%3A%2F%2Flocalhost%3A3000%2Fapi%2Fauth%2Fcallback%2Fline&client_id=

i solved this problem, but i don't understand why?
i just change providers array order in [...nextauth].js

-before
line provider doesn't work, it give empty client id

Twitter({
clientId: process.env.T_ID,
clientSecret: process.env.T_SECRET
}),
Line({
clientId: process.env.LINE_ID,
clientSecret: process.env.LINE_SECRET
}),
Google({
clientId: process.env.GOOGLE_ID,
clientSecret: process.env.GOOGLE_SECRET,
}),

-after

Line({
clientId: process.env.LINE_ID,
clientSecret: process.env.LINE_SECRET
}),
Twitter({
clientId: process.env.T_ID,
clientSecret: process.env.T_SECRET
}),
Google({
clientId: process.env.GOOGLE_ID,
clientSecret: process.env.GOOGLE_SECRET,
}),

it work!!! but i don't know why
