   <!-- Answer -->
   To resolve the 400 error when adding an Azure DevOps scope to an existing 
project with a GitHub connection, you need to ensure that the scope details and 
connection information are correctly mapped and validated. The error message 
indicates that the argument list is too long, which suggests that the payload 
size might be an issue.
   
   Here are some steps to address this:
   
   1. **Batch Processing**: Modify the `PutScopes` function to handle payloads 
in smaller batches to prevent the "argument list too long" error. Here is an 
example of how you might adjust the function:
   
       ```go
       func (gs *GenericScopeApiHelper[Conn, Scope, ScopeConfig]) 
PutScopes(input *plugin.ApiResourceInput, scopes []*Scope) ([]*ScopeRes[Scope, 
ScopeConfig], errors.Error) {
           params, err := gs.extractFromReqParam(input, false)
           if err != nil {
               return nil, err
           }
           err = gs.dbHelper.VerifyConnection(params.connectionId)
           if err != nil {
               return nil, errors.Default.Wrap(err, fmt.Sprintf("error 
verifying connection for connection ID %d", params.connectionId))
           }
           if len(scopes) == 0 {
               return nil, nil
           }
           err = gs.validatePrimaryKeys(scopes)
           if err != nil {
               return nil, err
           }
           now := time.Now()
           batchSize := 100 // Adjust the batch size as needed
           for i := 0; i < len(scopes); i += batchSize {
               end := i + batchSize
               if end > len(scopes) {
                   end = len(scopes)
               }
               batch := scopes[i:end]
               for _, scope := range batch {
                   gs.setScopeFields(scope, params.connectionId, &now, &now)
                   err = gs.verifyScope(scope, gs.validator)
                   if err != nil {
                       return nil, errors.Default.Wrap(err, "error verifying 
scope")
                   }
               }
               gs.setRawDataOrigin(batch...)
               err = gs.dbHelper.SaveScope(batch)
               if err != nil {
                   return nil, errors.Default.Wrap(err, "error saving scope")
               }
           }
           apiScopes, err := gs.addScopeConfig(scopes...)
           if err != nil {
               return nil, errors.Default.Wrap(err, "error associating scope 
config to scope")
           }
           return apiScopes, nil
       }
       ```
   
   2. **Scope Mapping**: Ensure that the `MapScopeDetails` function correctly 
maps the scope details for both Azure DevOps and GitHub. This function 
differentiates between scope details by checking the repository type and 
processing them accordingly.
   
       ```go
       for _, scope := range scopeDetails {
           azuredevopsRepo, scopeConfig := scope.Scope, scope.ScopeConfig
           if azuredevopsRepo.Type != models.RepositoryTypeADO {
               continue
           }
           id := 
didgen.NewDomainIdGenerator(&models.AzuredevopsRepo{}).Generate(connectionId, 
azuredevopsRepo.Id)
   
           if utils.StringsContains(scopeConfig.Entities, 
plugin.DOMAIN_TYPE_CODE_REVIEW) ||
               utils.StringsContains(scopeConfig.Entities, 
plugin.DOMAIN_TYPE_CODE) {
               scopeRepo := code.NewRepo(id, azuredevopsRepo.Name)
               sc = append(sc, scopeRepo)
           }
   
           if utils.StringsContains(scopeConfig.Entities, 
plugin.DOMAIN_TYPE_CICD) {
               scopeCICD := devops.NewCicdScope(id, azuredevopsRepo.Name)
               sc = append(sc, scopeCICD)
           }
   
           if utils.StringsContains(scopeConfig.Entities, 
plugin.DOMAIN_TYPE_TICKET) {
               scopeTicket := ticket.NewBoard(id, azuredevopsRepo.Name)
               sc = append(sc, scopeTicket)
           }
       }
   
       for _, scope := range scopeDetails {
           azuredevopsRepo, scopeConfig := scope.Scope, scope.ScopeConfig
           if azuredevopsRepo.Type == models.RepositoryTypeADO {
               continue
           }
           id := 
didgen.NewDomainIdGenerator(&models.AzuredevopsRepo{}).Generate(connectionId, 
azuredevopsRepo.Id)
   
           if utils.StringsContains(scopeConfig.Entities, 
plugin.DOMAIN_TYPE_CICD) {
               scopeCICD := devops.NewCicdScope(id, azuredevopsRepo.Name)
               sc = append(sc, scopeCICD)
           }
   
           if !azuredevopsRepo.IsPrivate && 
utils.StringsContains(scopeConfig.Entities, plugin.DOMAIN_TYPE_CODE) {
               scopeRepo := code.NewRepo(id, azuredevopsRepo.Name)
               sc = append(sc, scopeRepo)
           }
       }
       ```
   
   3. **Validation**: Ensure that the `PutScopes` function includes validation 
checks to verify the scope details and prevent oversized payloads.
   
   By implementing these changes, you should be able to resolve the 400 error 
and successfully add Azure DevOps scopes to an existing project with a GitHub 
connection
