CheckpointConnection.openRemote returns 403 error

[candcconsulting]

I am upgrading to 4.4
"@itwin/core-frontend": "^4.4.0",
however, when I use this line
const iModelConnection = await CheckpointConnection.openRemote(iTwinId, iModelId, iModelVersion);
I am getting this returned

errorNumber
: 
135168
isError
: 
true
message
: 
"Backend version 3.5.0 does not match frontend version 3.6.0 for RPC interface getConnectionProps."
name
: 
"RpcInterfaceStatus.IncompatibleVersion"

Is there a specific @itwin/core-frontend we should be using, or is there a way to connect to a 3.6.0 backend ... or ?

What backend are you pointing to?
Is it the visualization/imodel-access backend?

Hi @aruniverse
Not sure which backend I am pointing to. This is about connecting to an iModel without visualisation.

Here is my RPC initialisation

  const cloudRpcParams: BentleyCloudRpcParams = {
    info: { title: 'imodel/rpc', version: '' },
    uriPrefix: 'https://api.bentley.com',
  };
  BentleyCloudRpcManager.initializeClient(cloudRpcParams, rpcInterfaces);  
  
  /*const filter = (filters : any, tableState : any) => {
    console.log(tableState)
  } */

  const fetchClasses = React.useCallback(async () => {
    setIsLoading(true);
    try {      
      const iModelVersion = IModelVersion.latest()
      const iModelConnection = await CheckpointConnection.openRemote(iTwinId, iModelId, iModelVersion);
      const iModelClasses = await sqlAPI.getClassCount(iModelConnection);
      setClasses (iModelClasses ?? []);

When you initialize BentleyCloudRpcManager, change the version in cloudRpcParams to v4

Perfect that works now ... thanks so much

  const cloudRpcParams: BentleyCloudRpcParams = {
    info: { title: 'imodel/rpc', version: 'v4' },
    uriPrefix: 'https://api.bentley.com',
  };
  BentleyCloudRpcManager.initializeClient(cloudRpcParams, rpcInterfaces);
