In this case I deleted the project and reimported again, and didn't run into the same issue and I no longer have a copy of what the project tree looked like. Unfortunately I'm not sure what specifically went wrong on the first attempt.

When I right click on my main.flow file in Avaya OD Navigator, and select Orchestration Designer > Generate

I get the error message "Callflow code generator invoked on non-flow project."

The project is definitely a speech project, so why does OD not recognise it as one? What causes the error message to show? Is there a particular file missing?

I've worked this out. A process outside of AAOD on my computer had (accidentally) amended some files, causing Eclipse to not recognise the project properly. Presumably as a result of this, it was unable to verify the project version, so assumed it was out-of-date and it then tried to update it.

I closed and deleted the project from Eclipse, got a clean copy and reimported.

When I reopened Eclipse, it again prompted me to update, stating the imported project was out-of-date. This time it completed with no errors and builds seem to be working fine now.

Thanks

When I open AAOD, I get a dialog named "Upgrade Project" stating, "Project upgrade is about to run on workspace <full qualified name>, this is a non-reversible operation. Do you want to continue?"

If I click yes, I get an error with the following exception in the error log.

I have several questions:
Why do I need to upgrade project in the first place?
Why does the arithmetic exception occur (I don't have the code for this to look into it)?
I noticed a versioned method is called (updateCallflow_VERSION_05_25_07) is this the problem?
How do I stop seeing this error?

Thanks in advance.

Agreed, I don't think I've done this before. Is there a guide to how to do this?

From testing the scenario, I get these logs out even if the call doesn't end whilst in that sub-module. For example I get the logs out even for a call that continues for a few more minutes after entering and exiting the sub-module.

Do you know if there's any other instance that this error might occur?

Request is invalid sessionid [<redacted4>:/IVR] class [flow.Start] and saved class name [flow.<dialog3> is -> false

Unfortunately there are no further related logs or datetime stamps.

The lines of logging always appear 2 at a time and from testing, both lines are generated on the first pass through the dialog.

I've got an issue where we're seeing the below line of logging repeatedly:

Request is invalid session id [<sessionid>:<source>] class <start of flow> and saved class name [<class name> is -> false

I've established that the log seems to occur whenever I go to 3 specific dialogs. Interestingly when I do, the dialogs play fine, they take input fine and they progress the call fine - it seems there's no issue to the user, the only issue seems to be that we're getting logs!

I've searched previous posts in the forum but haven't found a situation that matches what we are seeing. It isn't the case that the user has hung up, as I have replicated the issue without needing to hang up.

Has anyone seen this before and worked out the cause? Any advice would be appreciated.
