How to setup hyperledger fabric explorer | Hyperledger Fabric consortium on Azure Kubernetes Service

I set up hyperledger fabric network by reading this document https://docs.microsoft.com/en-us/azure/blockchain/templates/hyperledger-fabric-consortium-azure-kubernetes-service. Network side everything worked properly. Now I wanted to set up hyperledger fabric explorer for this network. In order to do that, I did the follwing steps,
1. git clone https://github.com/hyperledger/blockchain-explorer.git
2. git checkout tags/v1.0.0-rc2
3. app/persistence/fabric/postgreSQL/db
4. ./createdb.sh
5. ./main.sh install
6. Replaced the connection profile (app/platform/fabric/connection-profile/first-network.json) like the following,

1. {
2. "certificateAuthorities": {
3. "ca.xxxxxxxxxxxxx.eastus.aksapp.io": {
4. "caName": "ca.org1",
5. "tlsCACerts": {
6. "pem": "-----BEGIN CERTIFICATE-----dfsajk-----END CERTIFICATE-----\n"
7. },
8. "url": "grpcs://ca.xxxxxxxxxxxxx.eastus.aksapp.io:443"
9. }
10. },
11. "client": {
12. "tlsEnable": true,
13. "adminUser": "admin.org1",
14. "adminPassword": "",
15. "enableAuthentication": false,
16. "connection": {
17. "timeout": {
18. "orderer": "300",
19. "peer": {
20. "endorser": "300"
21. }
22. }
23. },
24. "organization": "org1"
25. },
26. "channels": {
27. "hrschannel": {
28. "orderers": ["orderer1.yyyyyyyyyyyyyyyyyyyyy.eastus.aksapp.io"],
29. "peers": {
30. "peer1.xxxxxxxxxxxxx.eastus.aksapp.io": {}
31. }
32. }
33. },
34. "name": "org1",
35. "organizations": {
36. "org1": {
37. "certificateAuthorities": [
38. "org1CA"
39. ],
40. "mspid": "org1",
41. "peers": [
42. "peer1.xxxxxxxxxxxxx.eastus.aksapp.io"
43. ]
44. }
45. },
46. "peers": {
47. "peer1.xxxxxxxxxxxxx.eastus.aksapp.io": {
48. "grpcOptions": {
49. "hostnameOverride": "peer1.xxxxxxxxxxxxx.eastus.aksapp.io",
50. "ssl-target-name-override": "peer1.xxxxxxxxxxxxx.eastus.aksapp.io"
51. },
52. "tlsCACerts": {
53. "pem": "-----BEGIN CERTIFICATE-----jjdadjijfifawj-----END CERTIFICATE-----\n"
54. },
55. "url": "grpcs://peer1.xxxxxxxxxxxxx.eastus.aksapp.io:443"
56. }
57. },
58. "version": "1.0.0",
59. "wallet": "org1"
60. }

But I got the following error here tail -f logs/console/console-2020-07-08.log
