Bug in Metadata viewers

[dmachi]

If you go to https://net.science/files/resources/epihiper/examples/example_1/ there are two epihiper files loaded there. If you go to the metadata right hand panel, it crashes the UI.

Secondly, there are no default viewers for those types. Could you please add these to the default viewers. In fact, I think the current message of "No viewer available for files of this type" shouldn't be used. Instead, there should be a default viewer that is essentially the "text" viewer. This is only problematic for binary files, so we'll need to figure out that too. However, our default viewer could at least be everything except the "data" tab and allow the users to download.

• User would be able to view the metadata of the selected file, on click of metadata tab displayed in right pane
Note – Metadata tab would not be crashed on click of it.

• If the file manager config file does not contain the uploaded file type that is present in the file manager tab then the file type would be considered as “text” by default and “Text Viewer” would be used to display the file content.

• If any file attribute value in the metadata panel has the type object, JSONTree will be utilized to render the object in a tree-like structure so that it is in a readable format.

I reviewed this on ptest. For the default viewer as the text viewer, there is one issue. It should be if the filemanager config does not container the uploaded file type AND isContainer is false. The current implementation prevents you from going into "container" objects (like exceads experiment output).

This is mostly working now. Since the default viewer is text now, we have the opposite issue in at least one case....excel files. You can test this by uploading an excel file (type 'excel'). It will show the binary data on the data tab. My recommended solution for this would be to create a "blacklist" of file types that it will not attempt to render. It should still go to the file landing page, but it won't have a "data" tab (or a data tab with only the message about the file not being viewable in the browser).
