Invalid configuration file prototype error

[azuken]

Describe the bug Since 3.2.0 version, which introduce configuration validation, my app cannot be started.

My code :

new RollbarConfig(ApiKeys.ROLLBAR_TOKEN);

To Reproduce Update from 3.1.0 to 3.2.0

Expected behavior Rollbar initialized and application launched.

Rollbar Client - Rollbar.NET Hosting Environment (please complete the following information):

• Rollbar.NET Host type: mobile app
• OS and its version: Android 9
• .NET flavor and its version: .NET Standard
• Application framework and its version: Xamarin
• Rollbar.NET Version: 3.2.0

It was ID passed in Person DTO, we set this parameter to string.Empty but it must be filled.

@azuken, I am glad it worked out well for you. We recommend a code pattern where you create and initialize a RollbarConfig object, call Validate() on it to make sure it returns an empty result (no validation rules violated), then, use the config instance to configure a logger.

[azuken]

Yes, it will be done. But it would be great if the error message was more explicit about what it missing. Thank you anyway

[akornich]

@azuken , how exactly did the error message look in your case? In general, we have enums for validation errors mentioning property name and what wrong with it...

[azuken]

I have just a stacktrace with error message "invalid configuration file provided". Maybe it's just because we didn't implemented Validate()function.

[akornich]

@azuken , were there any inner exceptions included with it? normally, in such a scenario, I would expect an inner exception providing actual hints on what exactly could be wrong with the config...

Here is the complete stacktrace :

I'd like to poke this issue again. The same exception is being thrown now with no explicit description of what went wrong. It would be great to get the name/description of the validation rule which failed first included in the exception.

[akornich]

@viraptor , what version of the SDK are you using? It looks like you are getting RollbarException. Look at its Data property for the failed rules. They should be listed within the Data dictionary...

[viraptor]

Latest available (4.0.3)

[akornich]

Thanks, see my reply above about Data property of the exception.

[viraptor]

To be clear, yes, I get the details in Data. I'm just noting I'm another person who ended up here by googling for the exception message. The comment was a feature request to append one of the violations to the exception message as a quality of life improvement.

[akornich]

How about I'll add a hint "See Data property of this exception for validation details." to the exception message?

[viraptor]

Sounds good to me :)
