Configuring sentry sourcemaps for the twilio flex project template

[mster429]

I tried to configure sentry source maps for flex project template but ended up the errors reported still showing minified version of the code.
What i did was configure sentry to the project and added those manual steps to my custom pipeline to build the project before deploy and release

            - npm run build
            - npm run deploy -- --changelog="Deploy from CI/CD for commit ${BITBUCKET_COMMIT:0:7}" --description="Release from CI/CD for commit ${BITBUCKET_COMMIT:0:7}"
            - npm run release -- --name="Release from CI/CD for commit ${BITBUCKET_COMMIT:0:7}" --description="Release from CI/CD for commit ${BITBUCKET_COMMIT:0:7}"

and my build script was configured as follows

"build": "twilio flex:plugins:build && npm run sentry:sourcemaps",
"sentry:sourcemaps": "sentry-cli sourcemaps inject --org xxxxx --project xxxxxx ./build && sentry-cli sourcemaps upload --org xxxxx --project xxxxx ./build"

I would like to understand what I am doing wrong here. Any help is appreciated
Thanks in advance
