Oryx has failed to build the solution.

Yesterday my solution was building just fine. Made about 10 commits yesterday and each built and deployed fine. Now today I have come to continue my testing of Azure Static Web App and found that the solution is no longer building. Instead I get this error.


I first noticed the error when creating a pull request just now. I naturally assumed my code in the branch I pull requested from must have had a problem (even though it compiles and runs fine locally in Visual Studio). So I tried making a new branch based on the master branch (that I know compiled fine yesterday), made a small change to the README.md file and created a pull request... but same error.

So then I went to the master branch and just changed the README.md file to force a compile... but oh no, the same error! This code was pushed to the master branch just yesterday and compiled and deployed fine. Now I get this error with no changes made to the code or the Azure Static Web App portal.

What could be going on? What does this cryptic error even mean and where do I look for more information about what has gone wrong?
