Tag: Import

Hi, I'm trying to add a custom import functionality for my module, but this error appears:

Fatal error: Uncaught Error: Call to a member function getUrl() on null in E:xampphtdocsm2vendormagentoframeworkViewElementAbstractBlock.php:775 Stack trace: #0 E:xampphtdocsm2vendormagentomodule-backendBlockWidgetTabs.php(141): MagentoFrameworkViewElementAbstractBlock->getUrl() #1 (internal function): MagentoBackendBlockWidgetTabs->addTab('importpincode', 'netsmartz_pinco...') #2 E:xampphtdocsm2vendormagentoframeworkViewLayoutGeneratorBlock.php(298): call_user_func_array(Array, Array) #3 E:xampphtdocsm2vendormagentoframeworkViewLayoutGeneratorBlock.php(169): MagentoFrameworkViewLayoutGeneratorBlock->generateAction(Object(NetsmartzPincodeCheckerBlockAdminhtmlImportpincodeEditTabs), 'addTab', Array) #4 E:xampphtdocsm2vendormagentoframeworkViewLayoutGeneratorPool.php(81): MagentoFrameworkViewLayoutGeneratorBlock->process(Object(MagentoFrameworkViewLayoutReaderContext), Object(MagentoFrameworkViewLayoutGeneratorContext)) #5 E:xampphtdocsm2ve in E:xampphtdocsm2vendormagentoframeworkViewElementAbstractBlock.php on line 775

Here is my code: –

_assetRepo = $assetRepo;
    }
    /**
     * Prepare form
     *
     * @return $this
     */
    protected function _prepareForm()

    {

        $path = $this->_assetRepo->getUrl("vendor_module::importsample/sample.csv");

        $form = $this->_formFactory->create();
        $objectManager = MagentoFrameworkAppObjectManager::getInstance();
        $storemanager = $objectManager->create('MagentoStoreModelStoreManagerInterface');

        $fieldset = $form->addFieldset(
            'base_fieldset',
            (
                'legend' => __('Import Pincodes'),
                'class'  => 'fieldset-wide'
            )
        );

        $importdata_script  = $fieldset->addField(
            'file',
            'file',
            (
                'name'  => 'file',
                'label' => __('Upload File'),
                'title' => __('Upload File'),
                'required' => true,
            )
        );

        $importdata_script->setAfterElementHtml("
        Download Sample File
        ");

        $this->setForm($form);
        return parent::_prepareForm();
    }

    /**
     * Prepare label for tab
     *
     * @return string
     */
    public function getTabLabel()
    {
        return __('Import Pincodes');
    }

    /**
     * Prepare title for tab
     *
     * @return string
     */
    public function getTabTitle()
    {
        return $this->getTabLabel();
    }

    /**
     * Can show tab in tabs
     *
     * @return boolean
     */
    public function canShowTab()
    {
        return true;
    }

    /**
     * Tab is hidden
     *
     * @return boolean
     */
    public function isHidden()
    {
        return false;
    }
}

any help on this will be great
