Error: Source was empty #3

Closed NazirNoori44 closed 3 years ago

Getting an error when I tried to migrate. Here's the stack trace. I'm sure the source was not empty, there are valid categories and channels that exist so I'm not sure why it's giving that error.

Ok apparently the category and channels being migrated from server A must already exist on server B in order for this to work. Would be nice to identify that in the documentation. However it's migrating 0 messages, which is odd.

Ok apparently the parameters are messed up.

Guid1 is the server to transfer the messages to. (destination) Guid2 is the server to copy the messages from. (source)

The readme has it completely backwards. Probably a bug.

Thanks for the script though, saved me alot of time.

BilliAlpha commented 3 years ago

Seems odd, I could swear source guild is the first argument and destination the second. Would you mind posting the command you used along with the logs ? Thanks

Sushii002 commented 3 years ago

Hi there, I confirm that I had to switch the source and the destination in the command. And I also confirm that you need to create manually all the text channel in order to use the program without any errors. Could you please add it to the documentation please?

BilliAlpha commented 3 years ago

Sorry I didn't get back to you before. The arguments to the method migrateTextChannel where inverted due to the Tuple being inverted. This is now fixed in version 2.0.1
