#### **Setup Details:** We have set up a **Kubernetes environment on Minikube** to run **Canton components** , including: - `canton-domain` - `canton-participant` - `http-json` This setup was deployed using **Helm charts** on our local Minikube cluster. #### **Problem:** We successfully uploaded a **DAR file** to our **local participant ledger** using the following command: ```haskell daml ledger upload-dar --host=localhost --port=4001 .packages/data-dependencies/.daml/dist/sor-mvp-data-dependencies-1.2.6.dar ``` However, after deploying the DAR, we are **unable to see the expected templates** in **Daml Navigator** and when I visited the navigator page I could not see any templates from the package that I had uploaded to the participant. The navigator correctly populates the users so I know that it is able to connect to the party management service.’ Questions: What could be the possible reasons why the templates are not appearing in Navigator? How can we troubleshoot and resolve this issue given our Minikube-based Canton setup ---

To start the debugging, you could use the Daml Assistant to query for the packages. ```haskell daml packages list --host localhost --port 4001 ``` Does that list include your newly-uploaded packages? ---

I would try increasing the maximum gRPC message size. See the [Max Inbound Message Size](https://docs.daml.com/canton/usermanual/apis.html#max-inbound-message-size) docs for an example: ```haskell canton.participants.participant2.ledger-api { address = "127.0.0.1" port = 5021 max-inbound-message-size = 20971520 } ``` ---

@pratikkedia … as best I can tell the open-source Helm charts have not had that configuration included yet. Any chance you’d be willing to create a PR? [This recent PR](https://github.com/digital-asset/daml-helm-charts/pull/67/files) touched the same files. ---

@pratikkedia, no there is no other Helm charts repo for Canton 2.x, aside from the open-sourced, community-supported ones. ---

@pratikkedia … thank you for the Navigator screenshot and the output of `daml packages list`. One possibility is that Navigator is not looking at the ledger at port 4001. How are you starting Navigator? Is it with `daml start`, for example? ---

It appears that pod is starting a very old version of Navigator: ```haskell image: digitalasset/daml-sdk:1.18.1 ``` Try changing it to a 2.8.x SDK: ```haskell image: digitalasset/daml-sdk:2.8.12 ``` Or even the _latest_ SDK: ```haskell image: digitalasset/daml-sdk:2.10.0 ``` Do the templates then appear in Navigator?

Ah, right. I could have anticipated that for you. 🫠 So with 2.x, Canton added the concept of _users_ in addition to _parties_. - The default for Navigator 1.x was to login with _parties_. That’s why you see `participant::12203...` in the old version of Navigator. - The default for Navigator 2.x is to login with _users_. I’m _guessing_ that your participant is not yet configured with a user. Possibly that’s why the drop-down is empty. The two solutions for you are to either (1) setup _users_ in your participant or (2) tell Navigator to login with _parties_ instead of _users_. You can see the option to revert to the party-based login by running the following: ```haskell docker run -it --rm digitalasset/daml-sdk:2.10.0 daml navigator server --help ``` ```haskell Usage: navigator [server|dump-graphql-schema|create-config] [options] ... -h, --help prints this usage text : : --feature-user-management By default, the login screen is now populated by quering the user mgmt service. Disable to query party mgmt instead (the pre-2.0 default). ``` Try `--feature-user-management false` as a quick solution for using Navigator: ```haskell image: digitalasset/daml-sdk:2.10.0 command: ["daml", "navigator", "server", "–port", "7500", "--feature-user-management", "false"] args: ["zsor-participant-canton-participant", "4001"] ``` ---

We have recently encountered an issue while uploading DAR files to my Canton participant, and I wanted to share my experience . ### **Issue:** While uploading multiple DAR files to my Canton participant, one of the uploads failed with the following error: ```haskell An exception was thrown during the upload-dar command - GRPCIOTimeout ``` This occurred while uploading `sor-mvp-init-1.2.22.dar` , which is 5.1MB in size. The error message suggests that the DAR file size might exceed the gRPC maximum message size, which is typically set to 4MB by default. ### **My Setup:** - **Participant Configuration:** ```haskell ledger-api { address = "0.0.0.0" port = 4001 postgres-data-source.synchronous-commit = off max-inbound-message-size = 209715200 command-service.max-commands-in-flight = 100 max-contract-state-cache-size = 100 max-contract-key-state-cache-size = 100 max-transactions-in-memory-fan-out-buffer-size = 100 } ``` - **DAR File Sizes:** - `sor-mvp-data-dependencies-1.2.6.dar` ( Uploaded successfully) - `sor-mvp-models-1.2.22.dar` (Uploaded successfully) - `sor-mvp-integration-acord-1.2.0.dar` ( Uploaded successfully) - `sor-mvp-init-1.2.22.dar` ( Failed due to GRPCIOTimeout) ### **Possible Causes:** #### **1. Increase gRPC Maximum Message Size** Since my participant configuration already sets `max-inbound-message-size = 209715200` (200MB), the issue might not be the default 4MB limit I have set the max-inbound-message-size = 209715200 as we have discussed and we are using port forward cmd while we upload the dar daml ledger upload-dar --host=127.0.0.1 --port=4001 /Users/zinnia\_india/Documents/qa\_deployment/deleting\_daml\_backup/SOR-DAML/.packages/init/.daml/dist/sor-mvp-init-1.2.22.dar Port forward cmd kubectl port-forward svc/partcipant-service-name 4001:4001 -n canton and this cmd says connection lost and ledger participant pod get restarted when we upload dar ---

@pratikkedia Would you be willing to move your new question to a new post, since it’s not really related to Navigator? It’s just helpful in the long term to keep threads centered around a single topic. 🙂 ---
