Exception binding parameter - Unexpected character encountered while parsing value

[gpa]

We suffer from a bug introduced in v2.13.0, downgrading to 2.12.0 resolves the issue. Some durable activities are not able to start.

Exception while executing function: Functions.DA_update-request. Microsoft.Azure.WebJobs.Host: Exception binding parameter 'name'. Newtonsoft.Json: Unexpected character encountered while parsing value: {. Path '', line 1, position 1.

Can confirm reverting to function extension version 3.29.0 fixed the issue.

Update host.json

"extensionBundle": {
    "id": "Microsoft.Azure.Functions.ExtensionBundle",
    "version": "[3.29.0]"
}
