UI Builder -- Cannot find app

[Jack]

Hi Team,

We have already created an app shell via UI Builder for workspace (because we don't use App Engine plugin).

This workspace is worked but ,sometimes. we have to face with the issue when opening app via UI Builder

Error: Cannot find app xxxxxxxx

I known a workaround for this issue -- clear cache instance (cache.do)

I wonder if there is official solution to resolve this issue / OR Known Error related to this issue.

Could you please share with me if you have already fixed this before?

Hi

I suppose the xxxxxx stands for a Sys ID, right? Go to table sys_metadata to find the respective artifact and have a look into it. 

There is an article regarding that error message but I don't know it applies to you, as you did not provide more details: https://nowtektalk.blog/2021/02/24/uxf-framework-error-java-lang-nullpointerexception-null-value-in-...

Kind regards
Maik

Thanks Maik!

Yes, the xxxxxx stands for a Sys ID

I have checked  table sys_metadata and it looks good.

I will follow this article for checking when the issue occurred again.

NOTE,

Instance is using domain separation

Hi Jack,

Did you try the cache.do workaround (on a subprod) and it didn't work? This is a known issue internally but I don't think we've been able to determine a root cause yet. If this is one of your company instances opening a support case may help us out. Right now clearing the instance cache is the only workaround I'm aware of. If you'd like a more official answer and to link to the problem you'll likely need to contact support.

Hi Brad,

I try cache.do on sub-prod and it's worked.

I have already informed my team.

On my PDI, I have created similar app via App Engine Studio and I didn't see this issue (so far).

So, I wonder if there is any "strange" (behind the scene) when creating via UI Builder.
