AEMaaCS AC Tool is giving null pointer exception for yaml execution

[SDusane]

Hi All,

I need some help here, I am using AEMaaCS AC tool to apply the groups and permissions to it.

I have created some new groups and also updating the externalId for some existing groups in that yaml file, now when I am running this yaml file, its is giving me below error :

When I checked the logs I can see

Does Cloud service don't allow us to overwrite the existing user groups permissions?

Thanks,

@SDusane This is due to the incorrect format in the yaml file. 
look for provided spacing in the yaml file, there should be a space between a '-' and string.

Addition to that, you can check if all of your yamls have been resolved properly or not by using the URL below.

Hi @Rohit_Utreja ,

I have run the same yaml script on Dev without any issue but when I am running it on stage it is causing this issue. I suspect permissions issue on Stage.

However I recheck my yaml file and I don't find any syntax issue in it. 

Any other solution would be appreciated.

Thanks,

SD

@SDusane 
Are you still facing the issue?
and could you please share, how are you deploying the code to AEM (via pipeline would be preferred)
