An error occurred while saving the unsplit nucleotides with connecting with other monomers in the InChl, InChl AuxInfo, InChlKey

**Steps to Reproduce**
1. Open in micro mode
2. Add file with nucleotides and other monomers
[Schema nucleotide with sugar with different connections.ket.zip](https://github.com/user-attachments/files/16308860/Schema.nucleotide.with.sugar.with.different.connections.ket.zip)
4. Click on save to file in InChl (or InChl AuxInfo, InChlKey) format

**Expected behavior**
File is saved without errors

**Actual behavior**
An error occurred

With other connections is the same situation

Reproduce the failure in micro mode using the attached .ket schemas, then save each case as InChI, InChI AuxInfo, and InChIKey. Start by tracing the export path in Indigo and its WebAssembly build for unsplit nucleotide connections to other monomers. Done means all supplied schemas save without errors in each requested format.
