Launcher CNB_PLATFORM_API failed to get platform API version

[SAURABH110894]

Hi Team,

I'm using CNB Apache-Tomcat Image, It was all running fine before, but now we have updated to Apache Tomcat 9.0.82 and we are getting below error.

ERROR: failed to get platform API version; please set 'CNB_PLATFORM_API' to specify the desired platform API version

I'm using launcher, running certain command and triggering launcher /cnb/process/web command.

Could you please help me to fix this error.

@SAURABH110894 I believe this error is surfacing because you are calling the launcher with the launcher (/cnb/process/web is a symlink to the launcher). Can you try just /cnb/process/web?

@natalieparellano Looking for your support, I have kept error message on above message.

[natalieparellano]

@SAURABH110894 I'm afraid I don't have good insight into this error. Though the error message mentions the launcher, there is no indication what about it could be "wrong". Could you reach out to the Paketo team (slack.paketo.io)?

Thank you so much for Guidance !!!!
