Vega-Embed giving build error Cannot find name 'Extract' and 'Exclude' - vega

I created angular 6 application(Using node). In this application I used vega-embed. It is giving me compilation error.
import embed from 'vega-embed';
I also changed code in util.d.ts import stableStringify = require('json-stable-stringify') but giving following error
ERROR in node_modules/vega-lite/build/src/util.d.ts(58,41): error TS2304: Cannot find name 'Extract'.
node_modules/vega-lite/build/src/util.d.ts(73,58): error TS2304: Cannot find name 'Exclude'.

Getting "Connection is not recognized as a valid connection manager type" error in SSIS 2008 R2, but package runs fine

One of my primary SSIS import packages has been showing the following error the last few times it's been run. The data loads exactly how it should, just with this one error which doesn't seem to make a real difference. I would like to get it cleared up though.
Here is the error:
Error 1 Error loading Update.dtsx: The connection type "OLEDB" specified for connection manager "SQL.Staging" is not recognized as a valid connection manager type. This error is returned when an attempt is made to create a connection manager for an unknown connection type. Check the spelling in the connection type name. D:\SSIS Projects\Update.dtsx 1 1
Error 2 Error loading Update.dtsx: Error loading value " 0 SQL.Staging {925404E7-27AA-4C4E-337B-D6058341" from node "DTS:ConnectionManager". D:\SSIS Projects\Update.dtsx 1 1
Error 3 Error loading 'Update.dtsx' : The package failed to load due to error 0xC0010014 "One or more error occurred. There should be more specific errors preceding this one that explains the details of the errors. This message is used as a return value from functions that encounter errors.". This occurs when CPackage::LoadFromXML fails. . D:\SSIS Projects\Update.dtsx 1 1
As I said, the package runs fine. It doesn't seem to have any issues with the OLEDB source or destination's, which is what the error seems to indicate. Any other recommendations? Thanks!
