Upgraded 9.22 to 10.20 but now cant run JUNOS command scripts

I had recently upgraded from 9.22 to 10.20 for some new features but then it seems that I lost a lot more.  I am trying to run a command script to push configurations to Juniper JUNOS EX switches but it keeps failing with the same method as I did in 9.22 where it worked.

Select Device
Run Command Script
Juniper configuration
set system host-name testing
commit
Save

But this throws an error and it doesnt actually run

TypeError: com.rendition.util.StringUtils.explode is not a function in java_parser.js at line number 395

Did the format of entering how the script change?

hello bxscig , I`m now also upgrade from 9.22 version to version 10.00 first and then I will upgrade to higher versions my question to you how long time does this task take with you specially upgrading the DB because it take along time with me and my DB size = 52 GB is that normal or not ?

Hi,

I recommend you to open a case with support if you have a valid support contract, since that was reported a couple of days ago,

BR,

I have the same exact errors. they are not for just junos devices but for all command scripts. they all fail with that same error message.

Additionaly, check your Driver pack version, use the lastest then if the problem persists the error looks like a driver or JavaScriptBase driver bug

Cheers,

So we got the issue resolved, however our issue stemmed from having an older .rdp file in the following path:

/opt/NA/prod/server/lib/drivers/

/opt/NA/prod/server/lib/drivers/JavascriptBaseDriver-old.rdp
/opt/NA/prod/server/lib/drivers/JavascriptBaseDriver.rdp

By default it loads the first file in that directory path regardless of name so we were having all sorts of issues with it. Found out there can only be 1 file in there.

Support had provided a hotfix that was due to the Javascript driver that seems it affected more than just the Juniper driver.

Any other insights into the cause of this error?

I am encountering the same issue.  I don't have a JavascriptBaseDriver_old.rdp file and I'm running the latest version with the latest hotfixes (Network Automation 10.20.00.01 64-bit Build 261-071316+hf147115) and the latest driver pack (Build 8448-072616).

I have same error we updated 10.0 to 10.20

I have JavascriptBaseDriver_old.rdp Should I delete it?

After some tinkering and digging, I managed to fix the driver myself and have custom diagnostics and command scripts working again.  It looks like the javascript driver base is not compatible with the new interpreter (Nashorn) included in Java 8.  Here is what I did to fix it:

1. Unzip <NA-install-folder>/NA/server/lib/drivers/JavascriptBaseDriver.rdp.  Ignore the file extension.  It's a zip file.

2. Edit java_parser.js that was just unzipped.

3. Replace com.rendition.util.StringUtils.explode with com.rendition.util.BaseStringUtils.explode.

4. Replace com.rendition.util.StringUtils.implode with com.rendition.util.BaseStringUtils.implode.

5. Save your changes.

6. Zip the contents back into JavascriptBaseDriver.rdp.  Remember to backup your original, just in case.

7. Log into HPNA as an administrator and go to Admin -> Drivers.

8. Click Reload Drivers.  The JavascriptBaseDriver should be flagged as modified, but it will still use it.

Now try running a diagnostic or command script that uses a Javascript driver (Cisco IOS, Junos, F5, ...) and the TypeError should be gone.

Hope this helps until an official fix is released.
