Possible bug in spectrum

[martenreeh]

Could there be some bug in (the new version of) spectrum? I don't see where I can obtain the OPE or lambda of a fixed-x vector. It seems to just output something like

{
    "zeros":
      [
      ],
    "error": "3.454758966957157707376396366416383656106449573775604269577538038134155756314629827411604921638009520213765277182408071436510668902793057769924459441178074665931983101049853202482456808960034294158458280064057606422363788116736383566925873509412963146755133575701748377776"
  }

for the vector. I think spectrum is solving crossing correctly including the contribution from this fixed vector since the other OPE coefficients seem correct. Is it just not writing the lambda to the output for these fixed-x vectors? It has no zero since it is already a number, perhaps the code forgets to write the lambda in these cases?
