GuzzleHttp Exception: Unable to parse JSON data

I have not this error. Please find the install video. It is a new drupal 8.2.6 site. Installed first time the cmis module.
Video: https://youtu.be/sYNRXnwmCF4

My Alfresco version is Community - 5.2.0 (r130508-b9)

Please ask this question from cmis client developers (https://github.com/dkd/php-cmis-client/issues). I think if client is able to handle older version of Alfresco server this issue will resolve too.

@karamveersingh yes you need to upgrade to php 7 because dkd/php-cmis dev-master uses php 7 syntax.

@dj1999 hope you're doing well and reviewed my last messages, just a follow-up messages could you please tell me when I get the solution and response on my issue?

@karamveersingh unfortunatelly (or fortunatelly) the php-cmis client dev version fluently developing therefore this dev library and our 8.2-dev version is usable just for developing not for production.

Did you try the 8.1 drupal version? This use a stable php-cmis library and able connecting for example the Alfresco test repo.
Disable and remove cmis 8.2-dev module. Delete the cmis folder.
Download 8.1-dev module.
In cmis folder run command: composer require dkd/php-cmis
Enable cmis 8.1-dev module.

@dj1999 thanks for your messages/instructions, I followed same but sorry to say again prompted same error.

Error ->

Downloaded/configured CMIS 8.1-dev version see attached screenshot

Please suggest what else from my end?

Sorry for my english. My comment is ambiguous.

I had been meaned 8.1 version of CMIS API (https://www.drupal.org/project/cmis/releases/8.x-1.x-dev or git clone --branch 8.x-1.x https://git.drupal.org/project/cmis.git).

Please use the latest drupal 8 version and the 8.x-1.x-dev version from CMIS API.

@dj1999 thanks for your messages, tried suggested steps but sorry to say still facing same issue ->

Dkd\PhpCmis\Exception\CmisRuntimeException: cURL error 60: SSL certificate problem: self signed certificate in certificate chain in Dkd\PhpCmis\Bindings\Browser\AbstractBrowserBindingService->convertStatusCode() (line 342 of E:\wamp\www\drupal-8.1.3\modules\cmis\vendor\dkd\php-cmis\src\Bindings\Browser\AbstractBrowserBindingService.php).

I'm getting the same issue testing with both of the versions
- local installation, http://127.0.0.1:8080/alfresco/api/-default-/public/cmis/versions/1.1/br...
- and https://1ktudo.trial.alfresco.com/alfresco/api/-default-/public/cmis/ver...

The "Browse" functionality always returns with the message:

hello all,

any update on my issue? sorry to say problem open from last 2 months, please please help me

@karamveersingh
I checked this problem and found that something changed in libraries therefore cmis client queries not able to properly executing called from drupal module. Unfortunately I am very busy now and have not time to fix it. If somebody has time and send patch I'll put it to repo. Sorry!

anybody can help in this issue?
really appreciable if any can

@karamveersingh (and anybody else getting stuck here),
I was hoping to be able to use this module (and the dkd/php-cmis-client library) to connect to an existing Alfresco instance running 4.2.1 and have determined it's not going to work as expected. Wish I had a quick fix, but unfortunately, there is more to it. Hopefully, the following info is helpful in pointing you in the right direction:

Alfresco/CMIS Versions
Currently, the latest ("dev-master") version of the dkd/php-cmis-client lib only supports Browser binding, which requires CMIS version 1.1. If, like me, your Alfresco instance supports only CMIS version 1.0, the library will not work as is. You are getting this error because your endpoint is responding with XML-based AtomPub, rather than the simpler JSON-based response php-cmis-client is expecting.

8.x-2.x-dev
It DOES work with the latest dkd/php-cmis-client. But, again, only with CMIS 1.1. Installing with composer takes some workarounds, but the proof of concept does work with the example provided above.

So now what?
Since I'm dealing with this question at the moment, I thought I'd share.

1. BEST - If you are able to upgrade your Alfresco installation, that's what I would recommend most. The JSON binding in 1.1 is MUCH easier to work with, and all the cool kids use JSON these days :)
2. ALSO GOOD - You can try submitting an issue - or better yet a pull request - with https://github.com/dkd/php-cmis-client. The developers mention they aren't currently working on support for AtomPub. If I had time, I'd work on this, but I do not, so . . .
3. NOT GREAT BUT IF YOU GOTTA DO IT - roll your own using the 7.x version as your starting point. I considered this (basing off https://www.drupal.org/project/cmis/releases/7.x-2.x-dev), but I'm going to focus my efforts on option 1 at this time.

Thanks so much @dj1999! This is a great starting point and should be very useful for anybody who can use CMIS 1.1.

@markandrewsutton thanks for your time and explanation on my issue, this is really appreciable. Sure I will follow your instructions/suggestions and get back to you.

Confirmation: Is issue which I am facing , resolved from your end ? (FYI I am using CMIS/ALFRESCO on Drupal 8)
