I hit this problem months ago but was really busy and just put in a hack. Then I forgot about it and was bitten by this bug again. Figured I'd let you guys know about it this time.
I have an application with a SQL stored procedure that was exposed as an OData source on the server side. I then have a second (separate) app which is only a client, hooked up to the OData source from the first app. The code below is generated in the client app.
scheduling-odata.service.ts
spRegionsForProductsFunc(productContextId: string | null) {
return this.odata.get(/SpRegionsForProductsFunc(ProductContextID=${encodeURIComponent(productContextId)}), { });
}
Notice how the only parameter accepted by the odata function is a string. Also notice how the URL does not enclose the string value in quotes. This call results in a server-side error.
The following code works fine, with single quotes added. I've had to fix this manually.
return this.odata.get(`/SpRegionsForProductsFunc(ProductContextID='${encodeURIComponent(productContextId)}')`, { });
Let's get this fixed before it bites me, or someone else again. Let me know if you need additional info.
