Would you be able to provide more details on the dataset you are working on and the steps you have run prior to getting this error? |

I begin with a series of And the output: |

Is this NIRISS or NIRCAM data?

Until grism_prep and grp.drizzle_grism_models(), everything works well. I
have got a series of {root}-ir.[cat,seg].fits,*GrismFLT.fits ,
{root}_phot.fits ,{root}_phot_apcorr.fits so far.
Then this error appear when it comes to generate_fit_params( ).
Here's the code I am running:
files = glob.glob('*grism*png')
if len(files) == 0:
_ = grp.drizzle_grism_models(root=root, scale=0.08)
if not os.path.exists('fit_args.npy'):

args = auto_script.generate_fit_params(pline=pline, field_root=root, min_sens=0.0, min_mask=0.0)
And the output:

In the grizli/grizli/pipeline/photoz.py, I try to see the source code of photoz.eazy_photoz. So in the translate step, there's nothing comes out. |

My gut is telling me that you might be associating the incorrect direct image with the dispersed filter. But I don't work enough with NIRCam data to say much further. What is your observational set up? |

Hello! I am weiwwqeo's partner. We add the filters of the direct images such as

Great! Perhaps you can submit a PR with these fixes? @gbrammer are there missing filters that could cause this? |

I am a beginner and I have no idea how to resolve this problem.
