'Datasette' object has no attribute 'table_metadata'

[andig]

After importing a new table I'm getting

'Datasette' object has no attribute 'table_metadata'

when starting datasette and browsing to table. This is the backtrace:

Not sure what makes this specific table different from the others?

[andig]

Anything I can contribute to diagnose/fix this? Right now datasette (installed via Homebrew) is useless as it crashes on almost any table.

[tddschn]

Got the same error.

[simonw]

This looks like a bug in the GraphQL plugin. I'll take a look tomorrow.

[andig]

Would be great to get this fixed as it makes datasette unusable in this case.

[andig]

@simonw any update? I'm totally blocked on using datasette due to this error.

Friendly ping :)
