ParseError when solving systems with absolute values

[jarble]

On the demo page, I tried to solve this system of equations: solveEquations([abs(x)=8,x^2=64]) But Nerdamer shows an error message: Something went wrong. Nerdamer could not parse expression! ParseError: Cannot read properties of undefined (reading '1'): 1 Why is Nerdamer not able to solve this system?

The cause of the error has been fixed on the dev branch but it appears that there's still another issue that needs to be addressed since it gives 0 as the solution.
