PBI unable to detect custom data connectors #2

Open leungi opened 7 years ago

leungi commented 7 years ago

Chris,

I opened the sample pbix file, but can't see the custom connector as an option. Checking the queries, the following msg is seen:

Expression.Error: The import TextAnalytics.DetectLanguage matches no exports. Did you miss a module reference?

Look forward to testing it when it works! Thanks. Ivan

Sorry to ask this question, but you have installed the .mez file in the right directory, and enabled custom data connectors as a preview feature in Power BI Desktop? See https://powerbi.microsoft.com/en-us/blog/data-connectors-developer-preview/ for more details.

Chris,

Apologies for delayed response.

The .meq may be the issue. I already turned on feature preview.

I tried to compile the .sln file to generate .meq but no luck opening it; I use VS 2013, 2015, 2017, and all gave the same error message – ‘unsupported’.

Is it possible for you to compiled and post .meq to repo?

Thanks again for your help!

Ivan

Did you install the Power BI SDK for Visual Studio, as detailed in the Power BI blog post I linked to above?

Send me an email direct and I'll send you the file. You can find my contact details at www.crossjoin.co.uk

Thanks for the suggestion Chris; I should’ve installed the SDK first.

So I did, and got the .mez file. I placed it in ‘User\Documents\Microsoft Power BI Desktop\Custom Connectors’ as per guide, but PBI still can’t detect it.

Look FW to your advice.

Can you post the error message that you see when you try to run one of the queries from the .pbix file containing the examples?

leungi commented 7 years ago

There are 2 error messages when running the .pbix in the repo:

· missing module; likely due to PBI not detecting .mez file for some reason

Expression.Error: The import TextAnalytics.DetectLanguage matches no exports. Did you miss a module reference?

· Data source error; I presume this is a temp file that stores the results from API

DataSource.Error: Could not find a part of the path 'C:\Users\\AppData\Local\Microsoft\Windows\INetCache\IE\G6IAUWZW\feed[1]'.

Did you enable the Custom Data Connector preview feature in the Options dialog in Power BI Desktop?

leungi commented 7 years ago

Yes, first thing I did.

cwebbbi commented 7 years ago

I have no idea what the problem is then, sorry...!

leungi commented 7 years ago

No problem; you tried. Thanks again Chris. I’ll try to debug.

Did you find any resolution for the error @leungi ? I am seeing the same error for one of my custom data connectors

leungi commented 6 years ago

Haven't tried it again since. With the multiple updates on PBI thus far, it may just work now.

Will update when I have a chance to try.
