Example 19, SimpleMintToExample fails

[pcarvalho75]

Im running the examples but I fail to properly mint tokens by running the example 19 as provided in the solnet.

Im getting "System.NullReferenceException: 'Object reference not set to an instance of an object.' Solnet.Rpc.Core.Http.RequestResult.Result.get returned null." on line 159 of TransactionBuilderExample.cs

Could you please double-check on this?

Add initalAccount as a signer. The Memo Program requires the account to be a signer.

Dear Mario, Thanks for your reply. I have made some progress and managed to mint an NFT using metaplex as per the examples provided in your project. Here is a link to the mint. Please note the json points to an image. https://explorer.solana.com/address/2PkoVYtpnJFJe3uxEBCoB3de2K4BQjbzAyBsRA1JCY93/metadata?cluster=devnet I can’t get the image to show up in the Solana explorer, as for example, in this other NFT done by someone else: https://explorer.solana.com/address/5AAEo1Z4rK4LkrKJXYFjxQ6hmUgvse6qdtMDr1ihbh2J I don’t know where to start. would appreciate any help. I also can't get the master edition information to appear as per image. Any suggestions? [image: image.png] Many thanks, Paulo

everything's ok. Its the uri field. Its defined as http, so it gets blocked by the browser, because the explorer is https.

I have minted a new token, now with https. I have also installed https on the website, but the Solana explorer still can't see my logo. https://explorer.solana.com/address/2ztxGkMcRbH6jYWyfyTR1ZqSCDo5DFAaAXwnYX9qXu65/metadata?cluster=devnet Any further suggestions? Many thanks once again

In order for the tokens to be displayed on the explorers they need to be added to the Solana Token List

Edit: disregard comment above, I didn't see it was an NFT. There might be something that's interfering with the way it fetches the image url from arweave, I haven't spent that much time looking into this so I can't say for sure

[pcarvalho75]

But as this is a metaplex NFT, from my understanding, the solana explorer should be able to read the metadata and retrieve the logo; or am I wrong?

Everything is ok on my side. Tried in Edge and Firefox. The logo ( ntf image ) is displayed, metadata is ok... Also checked it on SolScan, everything is ok there too.

[pcarvalho75]
