I am using postman to access the Bulk API 2.0 and am trying to import mass PricebookEntries into a new Pricebook. It worked seamlessly on my ScratchOrg and now it says:
INSUFFICIENT_ACCESS_ON_CROSS_REFERENCE_ENTITY
Whole error for every object I tried to import:
"sf__Id","sf__Error",IsActive,UnitPrice,Product2Id,CurrencyIsoCode,Pricebook2Id
"","INSUFFICIENT_ACCESS_ON_CROSS_REFERENCE_ENTITY:insufficient access rights on cross-reference id:--","true","654.62","01t0E00000A74LWQAZ","EUR","01s1x000003CNm3AAG"
Any suggestions?
