What happened?

While working with HOP Web (Docker Installation Setup), when the user tries to copy the Transform from one Pipeline to Another Pipeline, we face the following error:

There was an unexpected error while copying data to the clipboard. org.eclipse.swt.SWTError: Cannot set data in clipboard at org.eclipse.swt.dnd.DND.error(DND.java:263) at org.eclipse.swt.dnd.DND.error(DND.java:219) at org.eclipse.swt.dnd.Clipboard.setContents(Clipboard.java:272) at org.apache.hop.ui.core.gui.GuiResource.toClipboard(GuiResource.java:1318) at org.apache.hop.ui.hopgui.file.pipeline.delegates.HopGuiPipelineClipboardDelegate.toClipboard(HopGuiPipelineClipboardDelegate.java:63) at org.apache.hop.ui.hopgui.file.pipeline.delegates.HopGuiPipelineClipboardDelegate.copySelected(HopGuiPipelineClipboardDelegate.java:340) at org.apache.hop.ui.hopgui.file.pipeline.HopGuiPipelineGraph.copySelectedToClipboard(HopGuiPipelineGraph.java:5221) at org.apache.hop.ui.hopgui.HopGui.menuEditCopySelected(HopGui.java:896) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at org.apache.hop.ui.core.gui.GuiMenuWidgets.executeMenuItem(GuiMenuWidgets.java:173) at org.apache.hop.ui.core.gui.GuiMenuWidgets.lambda$addMenuWidgets$0(GuiMenuWidgets.java:121) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:109) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:687) at org.eclipse.swt.widgets.Widget.notifyListeners(Widget.java:594) at org.eclipse.swt.widgets.MenuItem.handleAcceleratorActivation(MenuItem.java:687) at org.eclipse.swt.widgets.AcceleratorBinding.handleEvent(AcceleratorBinding.java:35) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:109) at org.eclipse.swt.widgets.Display.filterEvent(Display.java:1819) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:685) at org.eclipse.swt.widgets.Widget.notifyListeners(Widget.java:594) at org.eclipse.swt.widgets.Display.executeNextEvent(Display.java:1216) at org.eclipse.swt.widgets.Display.runPendingMessages(Display.java:1197) at org.eclipse.swt.widgets.Display.safeReadAndDispatch(Display.java:1180) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:1172) at org.eclipse.rap.rwt.application.AbstractEntryPoint.createUI(AbstractEntryPoint.java:69) at org.eclipse.rap.rwt.internal.lifecycle.RWTLifeCycle.createUI(RWTLifeCycle.java:177) at org.eclipse.rap.rwt.internal.lifecycle.RWTLifeCycle$UIThreadController.run(RWTLifeCycle.java:290) at java.base/java.lang.Thread.run(Thread.java:829) at org.eclipse.rap.rwt.internal.lifecycle.UIThread.run(UIThread.java:107)

Why? To minimize the development effort, an already configured Transform needs to be reused across multiple Pipelines. There is a need to copy/paste the Transform ('s) from one Pipeline to another Pipeline. However, on the HOP Web Ctrl+C / Ctrl+V OR Copy to Clipboard/Paste from the Clipboard is giving errors.

Reproduction Steps:-

1. Open HOP Web on the Web browser.

2. Open any existing Pipeline.

3. Select an existing Transform from the Canva and click the option Copy to Clipboard or Ctrl+C

4. Create a New Pipeline and click on the Canva and select option Paste from the Clipboard or Ctrl+V

HOP Web gives an Error message as shown below:

Note: The issue doesn't exist in the HOP client GUI

Could you try the following: Normally the first time you try to copy it will give you an option to allow it. But as it is marked as an unsecured website you might have to manually enable it.

Ah, I just noticed you are not on localhost. You will have to enable HTTPS it seems. Or use a workaround to mark the website as "secure"

Sure thing. Let us check that workaround and update the status.
