There was a problem analizing

[BMA]

I am getting this error There was a problem analizing, Error proccesing input when I am trying to upload a stl. I can open the STL with viewstl.com no problem. Any help? I have tried re-downloading the file and re-uploading. How do I fix this?

What I see:

[BMA]

I was able to slice it by opening it in the Buildplate and saving the design from there…

Will I have to do this everytime? It was very annoying trying to figure it out…
