I have set up a SharePoint tagged resource in the PLP (Pipeline Pilot) admin portal as per the guidance and through the Azure settings (perfomed by our IT security team).
The access rights for the tagged resource (name = PLP_SP) in the admin portal are set to 'Allow' for 'Everybody'. I have built a protocol (nmaed MAFRAF) in PLP which reads and takes specific data from an Excel spread sheet and to then produces a small table of the summarised data; this data then needs to be transferred to a SharePoint list in a specified SharePoint site. The list does not exist in the site and the idea was to get PLP to generate the list and populate with results. Every spread sheet that gets read by the protocol would then have the data populate the list, the list would grow over time. I have the SharePoint site set up, the resource connector component in PLP source is set to 'resource://PLP_SP/sites/NameOfSite'
I then set the protocol so the resource connector is triggered prior to the list writer:

 

I have run into an error at the resource connector step:

 Is this error related to how the tagged resource has been set up or is it something else? This is the error log (i have omitted my user name):
