Issue with coach core when using alongside sitespeed

Your question

So I have ubuntu 24 docker image and I am installing sitespeed in it. Few months ago the build were being built properly however when I tried today I faced below issue

tries to install @sitespeed.io/edgedriver which fails when I do a cloud build
To resolve this I did below change
RUN bash -c ". $NVM_DIR/nvm.sh && nvm use 20 && cd /tmp/coach-core && npm install --production --no-optional--loglevel verbose"
After this I faced below issue

mkdirp/terser missing because coach-core runs its prepare script (which requires devDependencies).
To resolve this I changed the command to below
RUN bash -c ". $NVM_DIR/nvm.sh && nvm use 20 && cd /tmp/coach-core && npm install --omit=optional --loglevel verbose"
Which revolves me back to edgedriver error. Any help with this as I had not faced this issue before. Were any changes made in package.json

I basically install replace actual coachcore with the forked coach core repo. But I was able to do this successfully few months ago. @soulgalore any advice on this?

Start with the Docker build commands in the issue and inspect coach-core's package.json, especially its optional dependencies and prepare script. Reproduce the build with npm install --production --no-optional and npm install --omit=optional, then identify why @sitespeed.io/edgedriver conflicts with the prepare dependencies. Done means the forked coach-core installs successfully alongside sitespeed without either reported failure.
