Issues viewing JEOL (jdf) Files via NMRium in Chemotion

[jnimoth]

• I am an ELNer

Expected Behavior

Jeol (jdf) files can be uploaded and processed inside the ELN using NMRium.
Jeol files are listed in the docs as being supported if NMRium is used (only not supported for ChemSpectra)

Current Behavior

After a Jeol file is uploaded, the NMRium button stays grayed out. The spectrum can't be viewed even with it.

Failure Information

If the same file is first converted to JCAMP-DX (jdx) format and then uploaded in the same way, the spectrum can be viewed with NMRium (but also ChemSpectra) as expected.

The same JEOL file (jdf) works if it is directly uploaded to https://app.nmrium.com/.

Steps to Reproduce

Attached is an example JEOL (jdf) file.

1. In a Chemotion v2.2.0 environemt with NMRium (e.g. Chemotion demo instance), upload the jdf file as dataset to the "Analyses" section of an experiment.
2. Select the correct type (1H NMR).
3. Save.
4. See if you can open it in Chemotion via NMRium as the documentation suggests.

Context

This was first detected in our own instance (v2.2.0), but I see the same in the public demo instance of Chemotion (also v2.2.0).

Failure Logs / Screenshots

I did not see directly any relevant logs.

This is how it looks for me (screnshot from the public demo instance):

This attached zip contains the JEOL (jdf) file that was used as well as the same file converted to JCAMP-DX (jdx).

It should be noted that I also tried other (1D) JEOL files. The behavior was always tje same.
