Internal Server Error on pipeline run

Hi, I'm trying to deploy my Angular static webapp through azure devops as a pipeline. The project works and builds with no issues locally but I'm encountering an Internal Server Error when I try to deploy it on Azure. This is the error message I get:

my pipeline (the default node.js pipeline except node version is changed to 14):
```
# Node.js with Angular
# Build a Node.js project that uses Angular.
# Add steps that analyze code, save build artifacts, deploy, and more:
# https://docs.microsoft.com/azure/devops/pipelines/languages/javascript

trigger:
- master

pool:
vmImage: ubuntu-latest

steps:
- task: NodeTool@0
inputs:
versionSpec: '14.x'
displayName: 'Install Node.js'

- script: |
npm install -g @angular/cli
npm install
ng build --prod
displayName: 'npm install and build'
```

I would like to provide more information but there isn't anything else stated with the error.
