Error occurs when export new model

Error occurs when export new model

Dear experts,

I was trying to generate events by using one new model.
This model is made by ourselves which aims to generate anomalous triple gauge couplings vertex.

the version I'm using is MG5_aMC_v3.0.0.beta

When I trying to generate events by run ./generate_events, error information will occur when compiling directory and before setting up grids.
But the generation can finished successfully even if with this error information, which means this error information will not affect the generation.

the error information is shown below:
Not able to open file /lustre/collider/liudanning/Generator/Madgraph/MG5_aMC_v3_0_0/NTGC-TEST/crossx.html since no program configured.Please set one in ./input/mg5_configuration.txt

  File "<string>", line 1, in <module>
NameError: name 'complexconjugate' is not defined

During the generation, I also use Pythia8 to do the hadronization and Delphes to simulate detector effects.

Thanks in advance.
