Okay Thanks..

Just to clarify - the fix worked in the environment where an existing instance of AQuAMan was running so it's not an (AQuAMan) application issue.

Regarding support for MSSQL - apologies, I do not have the scripts for any other DB other than MariaDB. 

Hello Stewart Burchell ,

Thanks for the update, recently we upgraded or local environment from 22.3 to 23.3 Appian Version. As checked with appian support team, they mention that the XPATH fix is part of the new version.

However, I am still getting the issue. Raised a Appian Support case to look that is it platform issue or Application?

Also, as I am installing Application in our local environment, and we have MSSQL DB. Can you please provide the scripts in MSSQL as well? 

Thanks

Hi sushilkapoor2418 

Apologies for the delay in relying, I've been out of the office.

I don't have a reference to the hotfix specifically but I do have a reference to a separate support case that you can mention: "612282 - Please make an incident for Xpath broken"

This should provide enough context for your support engineer to apply the relevant fix.

regards

Stewart

Hello Stewart Burchell ,

Can you please let us know the hotfix name or number  which is required to deploy in on premises server to fix the  

Hi - apologies for the slow response on this.

I have discovered that this is due to a change in a release of Appian that causes the fn!xpathdocument() to throw this error when introspecting into some (but not all) Process Models. There is a hotfix for this that you can raise with Appian support. Just mention the error and the fact that it is in the function mentioned and they can apply the hotfix to your environment.

How to resolve this AQUAMAN issue?

Hi Stewart,

Have you had the time to investigate on the issue? I am eagerly waiting for your feedback on the same.

Thanks,

Hi Stewart,

Thanks for your quick acknowledgement. Yeah we are seeing this error for all the process models. Whenever a patch contains a Process Model, this error is blocking the patch analysis. A patch without any process model is successfully processed by Aquaman.

We have further analysed and found that this error surfaced from 18th September, 2023. Prior to that it was all working fine.

FYI. We are currently on Appian Version: 23.2 and 23.3

Please find attached instance of the process model, I have used in examining in my second screenshot in earlier post.

Process Model.xml

Thanks,

Subhadeep

Hi Subhadeep

I am not seeing this/hearing about this anywhere else. Is it for all your process models or just the one that you are examining in your second screenshot? Are you able to send me an instance of one of your process models?

thanks

Stewart
