I'm using sp/pnp to update list items in a component based spfx web part.
We've tested timings and if the webpart is left for over 5 minutes then a 401 Unauthorized error is shown in the console when attempting to update a list item.
It doesn't happen in workbench.
Here is a list of npm packages in use:
I'm not sure it's caused by these but I've included them anyway.
I have other apps created in a similar way that don't have this timeout issue.
Facts:
- I have deployed the web part to a modern experience SP Online page.
- Before the 5 minutes 'timeout', it is possible to update a SharePoint list item
- I'm using the latest version of sp pnp (V3)
- The SharePoint permissions for the user(s) experiencing are a mixture of Full Control and Contribute (which is clearly enough!)
Has anyone encountered this issue?
