Channel-ordered (mu, sigma) tuples not saved via Serde package

[correac5]

I am trying to save a model I created as a .binpb file. I had used custom priors for each channel that were saved as a tuple, the model runs and can be saved as a .pkl file, but when I run meridian_serde.save_meridian(mmm, file_path), I get the following error:

2 meridian_serde.save_meridian(mmm, file_path)
