Server error: The system cannot find the file specified

[JanLektonen]

The last month my apps are beginning to produce red errors when starting app and also suddenly using the app or even in development in studio-web and studio-windows.

the error from the server when running the app is: "The system cannot find the file specified. clientRequestId: d50ccb8f-683b-a9f1-5bcb-173fdb84c952"

When I get the error in Studio for web og windows, a yellow mark is shown and red underline on the datasouce to SharePoint in the code. I can then refresh the datasouce and the error/yellow mark disapears. It appears on different datasouces arbitrary without any logic.

I have had an external culsultant to look into the errorlog that states something is wrong in the 'Blob cache'.

We have tried to clear the cache but the errors still continue to show.

Here is the event logged:

Any help on this is appriciated and right now the error is a showstopper for me and my users in the company.

Hi @JanLektonen,

What is your data source in this app? Is it a SharePoint library or list? What is the file that the error states? Please share more detailed configuration of your app so that I could try to create a similar to test.

Regards,

Mona

Hi @v-monli-msft

We use a Sharepoint 2016, latest version.Also we use the latest gateway install onpremise.

The datasouce is a Sharepoint list/table via a SharePoint Connection on premise.

When the error apear in the development studio the datasource-name(Sharepoint list) in the code gets marked(underline) suddenly as an error. I can then refresh the datasource and the data gets read again and the code is okay without yellow mark also.

Please let me know if you woul like more details

Please look at included pictures with the error before and after refresh.

Lookup fails on datasouce

After datasouce refresh in menu the lookup data lists correct again
