can we create custom modules like jwt , header-metadata  and using them in every gateway script and xslts and can we custom policy developed inside another custom policy?

Hi Santhoshkumar,
Yes you can.  To deploy them to your gateway the file will need to be in a gateway extension.  Then you'd just do a standard require to the path where you placed the file, ie local:///mypath/mymodule.js in your GatewayScript code that uses it.  The module can be used by any API, including within user defined policies.

Steve

Hi Santhoshkumar,
We've determined that this is a defect.  Please confirm in your case that you uploaded your user defined policy to your catalog.  We found in this case, you would get an error that the referenced UDP was not supported (actually not deployed) when it really was.  A fix is under development, but you really should open a PMR for this issue.  As a work around, if you deploy your UDP globally, it should deploy with no issue.  Since I already use a gateway extension with my gateway, I took my UDP yaml, included it in my gateway-extension.zip file, and updated the manifest.json file's section to add a reference to that file with a type of  user-defined-policy-yaml.  I then updated the gateway's gateway extension using the CMC Cloud Manager.

    "files": [      {        "filename": "forum-udp-in-udp.yaml",        "deploy": "immediate",        "type": "user-defined-policy-yaml"      },

yes , you are right , I uploaded on catalog level and when i try to use UDP in API is not getting deployed and giving the below error . I tried to deploy global level getting the different error. Please find files attached. I will create PMR .Kindly let me know if there is anything wrong with files attached.

Hi Santhoshkumar,

Thank you for opening the PMR.  So your previous post makes sense.  Your gateway extension doesn't have the std-post-invoke UDP deployed globally.  You're deploying nested-custmodule.yaml globally and it uses std-post-invoke, but you don't have std-post-invoke in your gateway extension.  To be on the safe side, ordering may also be important, so in your manifest, I'd have the dependent UDP std-post-invoke first so it would be deployed, then your nested-custmodule.yaml when it is deployed, std-post-invoke exists.  I must say you're breaking some new territory for me as my recreate was using the invoke_1.5.0 emulated policy which is in the deployed-policies section of the manifest and gets deployed first.  I was not using another custom UDP, but hopefully that will work if both are in the gateway extension.
Best Regards,
Steve Linn
