MultiChain-explorer no name Asset

Question

I get this error within multichain-explorer

Exception at 117484

I couldn't find anything here with this error, so I started debugging a bit the code. I reached the conclusion that one of my collegues issued an asset with no name.

I added a debug msg showing the content of val and it has no Asset Name

{'Quantity Multiple': 1, 'Open to follow-on issuance': False}

I thought is was our mistake, but then I found a question where you state that it is valid to issue Assets with no names.

So if I'm on the right track this seems like a bug. 

Now my explorer only shows me all the blocks until that no name asset was issued. In explorer is shows 250 blocks when we are at block number 283. And when I ask for listassets the  "assetref" : "251-301-36494"

Thanks in advance!

Thanks, this does look like a bug in the Explorer, which we'll fix in due course. For now please work around it by using some kind of dummy name for the asset. If you don't want to think too hard to create unique names, just try using the current unix time, or something like that.

Ok. we are starting a new alpha blockchain. We will keep in mind not to create nameless assets so the explorer doesnt break itself :)

This has now been fixed.  Thanks for reporting the issue!
