Running examples/browse.go returns EOF error

[Opsi]

I was trying to run the browse.go example against my Prosys OPC UA Simulation Server as well as a running production server and every time I get an EOF error. I usually start the browsing at the root node "i=84", but using the id of a FolderType node resulted in the same outcome. I also tried to run on a linux machine as well as my mac m1. The io.EOF err is returned whenever the code reaches this line of the browse code for the second time. After using a debugger it seems like the EOF error is created by this line in the secure channel code.

This is the corresponding debug output:

Progress on the issue:

• Browse and BrowseWithContext return a ua.BrowseResponse
• The NodeID from ua.BrowseResponse.Results[*].References[*].NodeID.NodeID have a NodeIDType of 64 (I'm unsure why)
• 64 is an invalid NodeIDType
• The next Browse or Read uses this NodeIDType=64 and the Server returns an error "Bad_DecodingError (code=0x80070000, description=\"Unexpected NodeId Encoding Byte 64\")" (Found with Breakpoint conn.go#L377)
• Then this error is hidden behind an EOF in secure_channel.go#L343 because len(b) == 0
