DataSource.Error: Web.Contents failed to get contents from URL (431): Request Header Fields Too Larg

[danielcontente]

Hi, 

Suddenly I started getting the following error when refreshing my data:
DataSource.Error: Web.Contents failed to get contents from URL (431): Request Header Fields Too Large
Details:
DataSourceKind=Salesforce
DataSourcePath=https://login.salesforce.com/

I would much appreciate if someone could help.

Thanks in advance

HTTP Error 431 which officially says "Request header fields too large," means the

server has dropped the request. The header sent by the user is either too long or

too large, and the server denies it.

If I understand correctly, the query with this request worked previously, and without

making any changes to the query it now fails when using the Salesforce Connectors that

are developed and maintained by Salesforce.com .

I encourage you to open an Issue at  Issues - Microsoft Fabric Community, and if this is more

urgent to open a Microsoft Support Case.

As a Salesforce customer, you have the ability to Create a Support Case

for individualized support or the ability to search for a related issue

or other documentation.
