Hello, I have created a custom Airtable extension. But accidentally  I deleted the extension connection from the Airtable base. So how can I run this extension on an Airtable base? Here is only a single option to add a new extension. There is no option to run the previous extension.
However, if I try to run by localhost:9000 it shows an error

{
  "error": "FORBIDDEN",
  "message": "blockId mismatch. Make sure you are entering development for the correct block."
}

Create a new custom extension "block", t hen update the blockId property in the remote.json of your project.

Hi @Jakewilson, I seem to have the same issue above. When looking through the directories I have no remote.json file. Can I only get the Id when setting up a new extension?

Did you ever find a solution for this?

I usually create a new extension and then copy the existing directory over instead if I ever hit this issue
