Blob storage connection API failing in Logic App after ARM template deployment

I have a standard logic app which uses the Create Blob v2 task. This creates a blob in a data lake container using an azureblob API connector.
It works fine when created via VSCode into my development environment, but I am having issues when I am trying to deploy to a test environment. I am deploying the azureblob API connector using the below template:
{
"$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"parameters": {
"connections_azureblob_name": {
"defaultValue": "azureblob",
"type": "String"
},
"storage_account_name": {
"defaultValue": "datalake",
"type": "String"
},
"location": {
"defaultValue": "uksouth",
"type": "String"
}
},
"variables": {
"storageAccountId": "[resourceId('Microsoft.Storage/storageAccounts', parameters('storage_account_name'))]"
},
"resources": [
{
"type": "Microsoft.Web/connections",
"apiVersion": "2016-06-01",
"name": "[parameters('connections_azureblob_name')]",
"location": "[parameters('location')]",
"kind": "V2",
"properties": {
"displayName": "hub-data-lake",
"api": {
"id": "[concat('/subscriptions/', subscription().subscriptionId, '/providers/Microsoft.Web/locations/uksouth/managedApis/', parameters('connections_azureblob_name'))]",
"type": "Microsoft.Web/locations/managedApis"
},
"parameterValues": {
"accountName": "[parameters('storage_account_name')]",
"accessKey": "[listKeys(variables('storageAccountId'),'2022-05-01').keys[0].value]"
},
"testLinks": []
}
}
],
"outputs": {
"azure-blob-connection-runtime-url": {
"type": "string",
"value": "[reference(concat('Microsoft.Web/connections/', parameters('connections_azureblob_name')), '2016-06-01', 'Full').properties.connectionRuntimeUrl]"
}
}
}
When I run the logic app workflow in the Test environment, I get a JWT token error:
Error from token exchange: Bad Key authorization token. Token must be a valid JWT signed with HS256\r\nInvalid JWT token. IDX12741: JWT: 'System.String' must have three segments (JWS) or five segments (JWE)
However, if I try to navigate the containers in the workflow designer, I am perfectly able to see and select containers:
Thanks
