Power Platform Community Forum Thread Details

I'm new to MS Power Apps, today I'm trying to use it to build a simple app: our team members can upload their documents with some extra notes, and the app will save them in a onedrive folder waiting for our accountants to process.

I'm in the first step of describing information as a table. But now Power Apps won't let me create this app, it always shows this error message:

Unable to create an app. Error: Failed to create entity with logical name cr1f1_cosmoinvoices and object type code -1. Exception: Microsoft.Crm.CrmSecurityException: SecLib::CheckPrivilege failed. User: c4256d94-4301-ef11-9f89-002248d40944, PrivilegeName: prvCreateEntity, PrivilegeId: 341e3ebf-74b8-4335-84f3-7f617bb7d081, Required Depth: Basic, BusinessUnitId: 036a5dc8-d81d-ee11-9967-002248e4a248, MetadataCache Privileges Count: 4915, User Privileges Count: 1251 at Microsoft.Crm.BusinessEntities.SecurityLibrary.ThrowPrivilegeDeniedException(IUser user, RolePrivilege rolePrivilege, ExecutionContext context) at Microsoft.Crm.BusinessEntities.SecurityLibrary.GetMaxPrivilegeDepthForUserAcrossBusinessUnits(Guid user, Guid privilege, ExecutionContext context) at Microsoft.Crm.BusinessEntities.SecurityLibrary.CheckPrivilegeGlobalDepth(Guid user, Guid privilege, ExecutionContext context) at Microsoft.Crm.Metadata.EntityService.<>c__DisplayClass58_0.<CreateInternalHelper>b__1() at Microsoft.Crm.SqlTelemetryHelper.LogSqlTimes(Action action, String operationName, IOrganizationRequestContext context) at Microsoft.Crm.Metadata.EntityService.CreateInternalHelper(EntityCreateInfo entityInfo, MetadataHelper metadataHelper, Boolean shouldCreateOnlyFromReserve, ExecutionContext context)

What is wrong with this?
