Data provider is not running in Selenium Grid

Can anyone please tell me that why the below error occurs: it occurs for all data provider methods. I use a static class for entire data providers and am using @Test(dataProvider = "Search", dataProviderClass= StaticProvider.class). it was running when i run normally with a test but on running Selenium Grid with 2 test all my data providers are throwing the below exception. I am running in sequential mode as i could not succed in parallel run.
