User class constructor throws exception
wolfstudy opened a new issue #5465: [Pulsar Functions] User class constructor throws exception
URL: https://github.com/apache/pulsar/issues/5465
**Describe the bug**
A few days ago, I could use this command to create a function instance correctly,
```
./bin/pulsar-admin functions create --retain-ordering --jar /Downloads/pulsar-util-function-api-pack-0.10.2-all.jar --classname ru.alfabank.api.utils.JournalBatchParseFunction --output-serde-classname ru.alfabank.api.utils.JournalBatchSerde --inputs test-input-topic --output test-output-topic --name test-serde-name
```
but now I re-use the same command, the creation fails, the error is as follows:
```
