Hey @Hi_p_Nguy_n_Van,
can you please go to \Documents\Power BI Desktop\Custom Connectors and make sure you only have Speckle.pqx. Installing the latest release would do that automatically.
After you make sure that you only have this file, OPEN A NEW POWER BI DASHBOARD and receive the data again. Don’t use the same dashboard.
In addition to @Nikos’s comments, a newer version of Power BI connector has been released. I recommend to install and use it 
I tried reinstalling, but got an error, please watch
Hey @Hi_p_Nguy_n_Van ,
Thanks for sharing the screen recording. Can you try the following:
Go to File > Options and settings > Data source settings.
Under Global Permissions, remove all Speckle related permissions. (app.speckle.systems etc.)
Then go to File > Options and settings > Options.
Select Security from the sidebar.
Under Authentication Browser, uncheck “Use my default web browser”.
Select OK.
Restart Power BI.
After you restart Power BI, go through the usual flow of loading a model from Speckle. Sign in with your Speckle account.
This seems to resolve this other issue. I hope it solves your issue too.
I just tried again, but still can’t fix it
As far as I can see from your recording, the checkbox for using default browser is still checked. Could you please uncheck it and try again?
I have connected to the model, but when I use the query methods to get the parameter, it fails, what to do next? Since the query method is now different from the previous video room[https://youtu.be/UbfekH8Htfc?t=802] , can I get a sample file?
Hi @Hi_p_Nguy_n_Van,
You need to spell the word correctly - parameters - and no pramters
Send us your Project URL and I can help you extract the parameters that you need.
