Unable to import any extension in ThingWorx 8.4

[rouellet99]

I just installed ThingWorx platform 8.4 with MSSQL as a persistant provider. The installation has been done with success. No error in the Tomcat as everything as stated properly. However, whenever I tried to import an Extension, I am getting a generic error like: Errors occurred during the validation or the import. There is nothing showed in the application log. Any idea how to solve or troubleshoot this issue?

[rouellet99]

I found the issue. There was a configuration issue under the platform setting to activate the extension capability.

Exactly for 8.4 version we need to provide extension import settings into Platform.json

Thanks for the psot

[Sugumar_5656]

This configuration is not functioning correctly.

Please suggest any other solution. My configuration is mentioned below,

	"ExtensionPackageImportPolicy": {
		"importEnabled": true,
		"allowJarResources": true,
		"allowJavascriptResources": true,
		"allowCSSResources": true,
		"allowJSONResources": true,
		"allowWebAppResources": true,
		"allowEntities": false,
		"allowExtensibleEntities": true
	}

Throwing error like,

In your Platform-settings.json file i can see 

"allowEntities": false,

try make this as true and check

"allowEntities": true,

in case importing this extension again gives error then try removing extension reference from system completely before the import.(sometimes extension reference still remains in system due to previous imports even it fails )

try understanding the error as well in application logs during import fails

[Sugumar_5656]

"allowEntities": true,

I included this code, still i am getting the same error which i mentioned above.

[rosharma · Accepted solution]

@Sugumar_5656 : Verify if this configuration is properly added to platform-settings.json file

(has to be a part of PlatformSettingsConfig as shown in below snippet)

//////////////////////////////////////

{
"PlatformSettingsConfig": {
"AdministratorUserSettings": {
"InitialPassword": "xxxxxxxxxxxxx"
},
"ExtensionPackageImportPolicy": {
"importEnabled": true,
"allowJarResources": true,
"allowJavascriptResources": true,
"allowCSSResources": true,
"allowJSONResources": true,
"allowWebAppResources": true,
"allowEntities": true,
"allowExtensibleEntities": true
}
}

[Thaveshni]

Please can you post your solution. We also have the same problem

[Sugumar_5656]

Still didn't find any solution for that problem, TWX 8.4 contains lots of bugs.

Better go with TWX 8.3.

[cd01]

I had the same errors. Mine was an issue with my platform-setting.json. I had placed the extension import policy settings outside of the platform settings config brackets. Here is my final setting file that worked for me...

{
"PlatformSettingsConfig":
{

"AdministratorUserSettings":
{

"InitialPassword": "xxxxxxxxxxxxxxxxxxxxxxxxx"
}
,
"ExtensionPackageImportPolicy":
{
"importEnabled": true,
"allowJarResources": true,
"allowJavascriptResources": true,
"allowCSSResources": true,
"allowJSONResources": true,
"allowWebAppResources": true,
"allowEntities": true,
"allowExtensibleEntities": true
}
},

"PersistenceProviderPackageConfigs":
{

"PostgresPersistenceProviderPackage":
{

"ConnectionInformation":
{

"jdbcUrl": "jdbc:postgresql://localhost:5432/thingworx",

"password": "xxxxxxxxxxxxx",

"username": "xxxxxxxxxxxx"

}

}

}

}

I'm getting the same issue in the latest release of 8.3 (SP5).  I've tried adding the "ExtensionPackageImportPolicy" to the platform settings file, but no luck.

Anyone have any updates?

[bmehringer]

Never mind, found my issue.  I didn't realize the Extension settings had to be in the PlatformSettingsConfig property group.

Moving this fixed my issue.
