Topic: Publisher Error: Snapshots not found?

I added a new dependency (de.medizininformatikinitiative.kerndatensatz.fall#0.9.1, from Simplifier) to one of my IGs. Now, the publishing process fails:
Using version 1.1.17

Is something wrong with the package or is it the publisher?

(The Resource in Question is a LogicalModel)

Ward Weistra (Sep 07 2020 at 14:28):

The IG Publisher trips over the resource in question not having the snapshot populated, which indeed seems to be the case: https://simplifier.net/packages/de.medizininformatikinitiative.kerndatensatz.fall/0.9.1/files/131316/~xml

A snapshot is not currently required for resources in packages, but it has been expressed that it is desirable. We will at some point start populating them by default.
I was under the impression that @Grahame Grieve had build something in the IG publisher that would automatically generate the snapshot if not found, but I'm not sure.

Jose Costa Teixeira (Sep 07 2020 at 19:42):

For Logical Models, i only use differential and the publisher does the rest

Grahame Grieve (Sep 07 2020 at 19:48):

I certainly expect snapshots to be generated on the fly. In fact, I don't understand that error. Can I reproduce this?

Noemi Deppenwiese (Sep 08 2020 at 08:37):

How to reproduce: Add this to SUSHI config.yaml:

dependencies:
  de.medizininformatikinitiative.kerndatensatz.fall:
    uri: https://simplifier.net/packages/de.medizininformatikinitiative.kerndatensatz.fall/0.9.1/files/131317
    version: 0.9.1

Tested it with the config generated by sushi --init.

Lloyd McKenzie (Sep 08 2020 at 13:40):

I'm now getting this with my 2016May builds - and nothing has changed there. So something has changed in the publisher @Grahame Grieve

Vassil Peytchev (Sep 08 2020 at 13:42):

Is that with the latest (1.1.19 as of now) version of the Publisher?

Grahame Grieve (Sep 08 2020 at 23:57):

I don't see how that works; I don't know how to convert that link into a package

Grahame Grieve (Sep 09 2020 at 00:36):

ok the reason that this fails is because the profile itself is invalid. The IG publisher is not presenting the error correctly; I have fixed that for the next release

Grahame Grieve (Sep 09 2020 at 00:36):

@Lloyd McKenzie this is not your problem

Lloyd McKenzie (Sep 09 2020 at 01:00):

I have a 'special' problem? :)

Grahame Grieve (Sep 09 2020 at 01:15):

yep. you have lots of invalid constraints

Grahame Grieve (Sep 09 2020 at 01:18):

but they didn't used to be an issue and I've found out why they've suddenly turned into an issue.
