Unknown error in XPath - Invalid Xpath Syntax

[SeanLapointe]

Hello,

I am building an Adaptive form, and I noticed that I was getting some errors in the log when I render the form in the Workspace UI. I am getting this error on two different tables and two different check boxes. Despite the errors, the fields are displayed properly and the fields with rules and behaviors do what they are supposed to do. I tried deleting the fields and remaking them, but that didn't stop the errors from happening. Does anyone have any suggestions?

Here is an example of the error message:

[Mayank_Tiwari]

@SeanLapointe Are you able to submit the form in Workspace? If you are not facing any functional issue, then you may ignore this error.

Also, few points to check:

1. if you are on Unix, please make sure you have installed all the 32 bit libs, as per [0]. 

2. check if all the OSGi bundles are active.

3. try reinstalling the Forms add-on package and restart the instance.

Thank you. My system is Windows based. The form has failed to submit a couple of times, but I think it might have been an unrelated bug that I have since fixed.

Every form render in DEV adds about 20MB to the error log, so if I were to push this form to production, it would increase the log size by about 20GB a day. Is it safe or even wise to have logs that big? It has to be difficult to look through an error log that big to trouble shoot issues.

If you are saying that I can signore these messages, does that mean you know what causes them? Can you provide any details? I would prefer to not have errors.

[Mayank_Tiwari]

You mean you can submit the form now? Have you enabled any debug logs?

Can you please share the form's package and its dependencies, if any, so that I can test it at my end? Are all the OSGi bundles active?

[SeanLapointe]

All bundles are active. When it failed to submit, there was no error message. I believe that this problem was due to a coding error (mistakenly set a hidden empty field as required) has been fixed.

I can share the package, but how do I upload it? When I try to attach it to this post, it says zip files are unsupported.

[Mayank_Tiwari]

You may use Google drive link to share. Also, please confirm, have you enabled any debug logging?

[SeanLapointe]

I am not sure? How can I tell if I enabled debug logging?

[Mayank_Tiwari]

Please send your form here - maytiwar@adobe.com.

Note: please rename the attachment's extension to .adobe to avoid it getting blocked while sending through email.

I tested your form on my server, and I am not getting any such error as you are getting, while rendering the form in Workspace. Also, it is not adding even 50 KB of logs while rendering at my side. Can you also share your complete logs generated while rendering the form in workspace?

[SeanLapointe]

Here is a link to todays log.

I believe the first error comes up at timestamp 01.11.2021 13:27:05.342

Which version of AEM Forms you are testing this on? And have you applied any service pack? I can see WCMDebugFilter in the shared logs 3046 times. I am not seeing it at all in my logs. Is it possible for you to test the same form on a fresh AEM Forms instance, or try to rebuild your crx-repository?

[SeanLapointe]

We are using AEM Forms (JEE) version 6.5.7

It would take me a number of days to spin up a fresh AEM forms instance. I can upload this form to a different server that we already have up and running though..

[Mayank_Tiwari]

Yes, please test the form on a different server, or try rebuilding the crx-repository(won't take more than 30 min) on the existing server, as the issue is not with the form, but with your instance, or I would have also faced the same issue.

[SeanLapointe]

I will do that, thank you.

Are there instructions on how to rebuild the CRX repository on the Adobe site somewhere?

[Mayank_Tiwari]

Here are the instructions:

1. Stop AEM Forms server.

2. Take the back up of crx-repo.

3. delete all the folders in crx-repo, except "install" folder.

4. Start AEM Forms server.

5. Wait until error.log get stabilized.

6. check if all the bundles are active.

7. Restart AEM Forms server

Note: this will wipe out the Service pack(6.5.7) applied. You would need to apply it again, along with the Forms add-on package.

[SeanLapointe]

I added the form to a different server and also added the relevant processes to workbench. When I render the form in the Workspace UI on this new server, I am still getting these error messages.

[Mayank_Tiwari]

Can you please log a Support ticket for this, as it requires deeper investigation? Thanks.

[SeanLapointe · Accepted solution]

In case anyone wants to know what happened here, this is the error message you receive when you have an adaptive form that uses an xsd schema and you add an unbound control to the form. You can either live with the error message, or bind it to an element in your schema.
