Dear everyone,

Log in to the front-end page, an error is reported, the circled place in my picture shows the value as none, what is the reason for this?

Best regards,

Can you paste the contents of your beamline.yml file ?

Dear @marcus-oscarsson ,
Below is the content of my beamline_config.yml profile, thank you.

_initialise_class:
    class: mxcubecore.HardwareObjects.Beamline.Beamline
    # Further key-value pairs here will be passed to the class init

# objects
#
# Eventually all objects should use the yaml config system like Beamline,
# but for now we can leave them as xml
#
# NBNB some objects that do not currently have their own config files
# would need those added (e.g. the centring methods)
#
_objects:
    # The !!o0map and the lines starting with '- ' give you an *orderd* dictionary
    # And thus a reproducible loading order
    !!omap
    # The values are the file paths to the configuration file for the
    # object, relative to the configuration file path(s)
    #
    # NB - the order is *NOT* arbitrary, as signal connnections are set
    # on one object that require the other to be already loaded.

Dear @Baokangwen, looking at your configuration file, I have few questions/comments:

• do you try to run MXCuBE on a real beamline or with the mockup classes?
• do you do energy scan and XRF - if not, put them as False
• you should remove everything which concerns the undulators - what I see is very ESRF specific.

[Baokangwen]

Dear @marcus-oscarsson,
Thanks for your replying.
I run MXCuBE on a real beamline,I changed it according to the ESRF configuration file, I modified it according to your requirements, I added "mesh:True" to the configuration file, and solved the error.
