Hello,
     I encountered the following problems when using system4.4. I checked the information for a long time but did not find a relevant solution. I would like to ask if I can give me some ideas to solve it.
     The simple example of printing hello world can be executed normally, but I give a script file, which is mainly used to record the information triggered by a given docker during the execution process and report errors.
     The following is the execution process, and the attachment is the execution script.(I thought it was a version problem, so I switched to the system4.4 version and tried again, but the same error was reported )
     Hope you can give me some solutions, thank you very much! :)
