This may happen if an object previously installed by Composer was deleted

Dear All,

Does anyone know how to resolve following error which I get during:
Dar file installation :

Error retrieving object Id. This may happen if an object previously installed by Composer was deleted. Object reference will be returned null.

Thanks in advance.

I've seen this error coming up a couple of times. Usually, if I re-install the DAR after seeing it, it works....

It is not working as I am trying to reinstall the dar file and it fails to install giving the same error.

Does anyone have solution to this problem.
?

Further for xForm is it OK and safe to change r_immutable_flag value for dm_xfm_resource? As it is not letting me save the object which is immutable and hence dar installation fails?

Since as mention in another answer, the application JAR file is actually an XML file, you could try to edit it and remove the object giving the error in it, then try to reinstall.

That's certainly not something EMC would recommend to do but who knows , it might do the trick for you....

Not sure about this one but if you're on a dev or test environment, you could give it a try.

then again, if it tries to overwrite the version which is already in the repository, that might means you need to modify you composer project to version the artifacts instead of overwriting them, this way, you shouldn't have any problems with immutable objects.....
