Issue with `ids_put` validation for `plasma_profiles` IDS in Matlab

[Fleury-dev]

Description:
When writing plasma_profiles using ids_put under Matlab, this error occurs:

Warning: IDS plasma_profiles is found to be invalid. PUT quits with no action.
In metis4imas (line 1697)
Error using ids_put: internal error of type HLI occured.

The specific reason for the validation failure, which fields are invalid according to the validation rules are not displayed, making it difficult to diagnose the root cause of the invalidity.

Environment / Version:

IMAS :

AL: 5.4.3
DD: 4.0.0
Matlab: 2020b

METIS : develop branch
METIS repo:** GitLab or
ITER Git

• Note: No compilation is required after cloning for this specific test.

Steps to Reproduce:

1. Clone the develop branch of METIS.
2. Navigate to the root directory of the installation.
3. Run the following commands:

touch arch.inc
make testimasinmetis

Traceability:
The error occurs at line 1697 in metis4imas.m:

1697: ids_put(expIdx, strrep(nids,'core_','plasma_'), core_profiles);

Hi @Fleury-dev, thanks for the nice reporting!

The validation reporting in IMAS-Matlab was corrected only in release 5.5.0 (but I'm surprised that you face this issue because this fix also concerned the fact that the validation routine was not called from the put in Matlab), can you try with this last version?

Also note that there was a bug we encountered in the DD in plasma_profiles coordinates (cf. iterorganization/IMAS-Data-Dictionary#194), this may be related to the problem you are facing. A patch for the DD was released as 4.1.1.

@Fleury-dev I followed the steps on SDCC. Please find the log below. Did it go through successfully?
Note: I used MATLAB/2023b, as MATLAB/2020b is not available on SDCC.

@Fleury-dev Do you have any update on this? Thank you

Hi @prasad-sawantdesai ,
I'm currently out of office. I will review this issue again when I return. Thanks.
