error for importing extensions into ThingWorx9.4 , looks like Compatibility problem of imported jar

[千松_10631492]

Hi,

I try to import a extension to ThingWorx9.4. but import failed with errors looks like some Compatibility problems of jar in extension package.  These problems had not happened with ThingWorx9.3. 

What should I do with ThingWorx9.4 ?

Here is the logs

Hi,

Two reasons

1. The old extension still exists

2. Or Restart the server and try again !

Thanks,

Hi @千松_10631492 

Could you please provide the application log while importing the extension?

Hi @千松_10631492.

We noticed this error in the log:

2023-08-23 10:28:50.796+0000 [L: ERROR] [O: c.t.e.u.ResourceUtilities] [I: ] [U: SuperUser] [S: ] [P: ] [T: ajp-nio-127.0.0.1-8009-exec-9] Unable To Create Resource Instance From Class: com.xxx.xxxx.resources.Functions

Notice the bold.  Did you forget to update it to the correct name?

Regards.
