Calculations give meaningless errors for in-line SMILES molecules

[ClairePA]

The HELM string RNA1{R([NC1=NC(N([*:1])C=C1)=O])P}$$$$ is valid and is accepted by the webeditor. Some of these calculations give errors incorrectly and some errors are not descriptive, and only show the user gibberish. All errors should show a meaningful description, but most of these calculations should be performed.

The HELM string PEPTIDE1{[C(=O)[C@H](C)N([*:1])C]}$$$$ is accepted and all calculations are performed correctly.

The web-services calculations give the following results:

• validate: valid
• convert into canonical HELM: error

Retested and the errors are still the same.
