"UnexpectedValueException" on yii2 composer update - yii2

Question

Got "UnexpectedValueException" Your github oauth token for github.com contains invalid characters:"" while composer update on yii2 project.
When i was installing jui datetimepicker via composer, I have asked to give git token to install it. I had generated the token from GitLab and provide the token to terminal.I also change the composer.json file with token. But it gives me an error of "UnexpectedValueException" Your github oauth token for github.com contains invalid characters.
I have tried following solutions :
1) I have deleted my .git folder and tried to update composer still same issue
2) I have deleted the vendor and reinstall the composer not worked.
3) I have deleted the vendor and composer.json and put the previous vendor and composer.json file from my backup. but still get same issue.
4) I have tried to change the token from the following code :
composer config --global github-oauth.github.com <TOKEN>
5) Also put the following code in composer.json :
{
"config": {
"github-oauth": {
"github.com": "<TOKEN>"
}
}
}
Still same issue.
My composer.json file is as follows :

I'm not sure what was the reason why it stopped working for you but as we discussed in comments the solution was to update the entry in auth.json that stores this GitHub token.
For everyone looking for this solution - auth.json is stored in your COMPOSER_HOME path. You can find this path by calling in the console
composer config -g data-dir
For more information about Composer configuration please refer to the Composer documentation at getcomposer.org.
