Keep getting "IndexError: list index out of range" in vinfo.py

[davehouser1]

Full error:

  File "/home/bob/.local/lib/python3.6/site-packages/rvtools/vinfo/vinfo.py", line 8, in get_obj
    obj = container.view[0].name
IndexError: list index out of range

Here is the function where it is failing:

def get_obj(content, vimtype):
    obj = None
    container = content.viewManager.CreateContainerView(content.rootFolder, vimtype, True)
    obj = container.view[0].name
    # for c in container.view:
    #     if name:
    #         if c.name == name:
    #             obj = c
    #             break
    #     else:
    #         obj = c
    #         break
    return obj

Trouble shooting:

• Tried using the ~/.rvtools conf file, also used directly inline.
• Edited vinfo.py to do some print statements to backtrack, Here is the function, added the following print statements:

def get_obj(content, vimtype):
    obj = None
    container = content.viewManager.CreateContainerView(content.rootFolder, vimtype, True)
    print("!!!!!!!!!!!!!!1")
    print(container.view[0].name)
    print("!!!!!!!!!!!!!!2")
    obj = container.view[0].name
    # for c in container.view:
    #     if name:
    #         if c.name == name:
    #             obj = c
    #             break
    #     else:
    #         obj = c
    #         break
    return obj

Here is the output I get now:

IndexError: list index out of range

• Note when I force the string "MyDataCenter" into "datacenter" for line 358, then the error appears on line 636 for the cluster.

Workaround

• I ended up not using the "get_obj" function, and just defined my datacenter and cluster names as strings. This seemed to work. Also not we do not have a cluster, our hosts are attached directly to the datacenter (Wonder if this is the issue?), I put "none" for cluster.

I am not a python guru, so any feedback you could provide would be helpful. It looks like the function is trying to pull the datacenter name out of the object, and it looks like it succeeds based on the sytnax container.view[0].name, but for whatever reason the get_obj function fails.

Hey @bugcy013

Are you using the binary version available here ?

Thank you! Waldirio

[eyryve]

Hello. This error appends when there is no cluster defined. Here: cluster = get_obj(content, [vim.ClusterComputeResource]) print("Cluster: {}".format(cluster)) vinfo_data['cluster'] = str(cluster)

lastest version do not fix this issue.

Bye.

Hello @bugcy013 @Rajeshunix13 @davehouser1 and @eyryve

I pushed one new version via pip, with that said, you can update the package and try once again.

Please, let me know if you are still facing issues, then I'll move on.

Thank you for your help and sorry for my delay. Waldirio
