Unable to submit project solution

I’m trying to submit the solution for project “Build a Celestial Bodies Database” in relational databases course in freeCodeCamp site. I put my github repo link where solution files are, but it says “You must complete the project first.”

I don’t get this error meaning??? Can anybody help me out and what should I do here?

Please follow the debugging steps here:

I have already tried everything mentioned in the debugging steps and I had created a thread about this a week ago here, mentioning the exact issues I’m facing.

“Test runner failed” - Backend Development - The freeCodeCamp Forum

have you tried deleting the VM and recreating it? and trying to pass the tests in it?

Yes, even after recreating VM the tests wont pass
