Why won't gulp run through MSBuild in Develop configuration?

Question

I have a project which uses a gulpfile.js, and have set it to run gulp before build:

<Target Name="GulpBuildDevelop" BeforeTargets="BeforeBuild" Condition="'$(Configuration)'=='Develop'">
        <Exec Command="npm install gulp" />
        <Exec Command="gulp build-development" />
    </Target>
    <Target Name="GulpBuildUAT" BeforeTargets="BeforeBuild" Condition="'$(Configuration)'=='UAT'">
        <Exec Command="npm install gulp" />
        <Exec Command="gulp build-release" />
    </Target>
    <Target Name="GulpBuildRelease" BeforeTargets="BeforeBuild" Condition="'$(Configuration)'=='Release'">
        <Exec Command="npm install gulp" />
        <Exec Command="gulp build-development" />
    </Target>

I am building using MSBuild on the Jenkins server, running on push. All the projects are on the same server, just different directories. In UAT and Release everything runs as expected:

    GulpBuildRelease:
  npm install gulp

  To address all issues (including breaking changes), run:
    npm audit fix --force

  gulp build-development

However, in the Develop branch, the install runs differently and it errors saying it cannot run gulp:

GulpBuildDevelop:
  npm install gulp

I have tried running npm install -g gulp, tried specifying the working directory, nothing has worked.
