Bitbucket Pipeline fails with: JavaScript heap out of memory

I'm trying to run a build of an Angular template app I bought. I have setup the pipeline as follows:


image: gabrielaraujof/angular-cli

    - step:
          - npm install
          - ng build --prod
          - tar -zcvf package.tar.gz dist/
          - curl -X POST --user "${BB_AUTH_STRING}" "${BITBUCKET_REPO_OWNER}/${BITBUCKET_REPO_SLUG}/downloads" --form files=@"package.tar.gz"

Now this actually works fine.


However when I add the (for me required) `--prod` flag the process ends with some "Javascript heap out of memory" exception (see below for full trace).

Now I haven't changed any parts of the template yet. Does this mean Bitbucket Pipelines cannot build this project or should I keep trying until there is enough memory?

(i only have 9 build minutes left from the trial as this last failed build took over 19 minutes..)

By default the memory limit in Node.js is 512 mb.

To solve this issue you need to increase the memory limit by adding the following line to your step script:

- export NODE_OPTIONS=--max_old_space_size=3072

 Note that the memory limit was set to 3gb, but that number is up to you. By default pipelines containers have 4gb.


Anyone found any fix for this ? I am getting this error as well. I have tried the following:

-max_old_space_size= (tried, 4gb, 8gb, 10gb)


bitbuket pipelines yml file

All steps have 2x size set for 8gb and even I have found and tried the options before the steps definitions
 size: 2x

Sometimes the error still happens, re running the pipeline will work randomly.


It looks like the correct line to add is:

- export NODE_OPTIONS=--max-old-space-size=3072

You can change 3072 to 6144 if you enable the 2x size in your pipeline settings.

Note the dashes in max-old-space-size instead of max_old_space_size mentioned in previous comments.

Official docs:


In my case it was wrong configuration in my bitbucket pipelines I had the following option set

    memory: 5120


Thinking that this would allow more memory in fact it was on the contrary this was allocating 5GB to the docker container and leaving 3GB for the build container, I removed the setting which allocates 1GB for docker container and remaining for build container thus my build now never fails with javascript heap out of memory.

I am getting same issue. How you did this, can you please share your pipeline. Thanks.

I have set the following,

size: 2x script: - export NODE_OPTIONS=--max_old_space_size=7072

and i am still seeing FATAL ERROR: invalid array length Allocation failed - JavaScript heap out of memory


Any help would be appreciated. 

Hello Shanmuga,


Did you find a solution for the error?

A subsequent call did build correctly

I’ve got he same issue when NOT adding `—prod`. It use to build in a second or even third run, but now it just doesn’t anymore.

Update: I thought of increasing the step size but it is already at 2x. I doubt 8gb are not enough for building a medium-sized angular project.

any resolution for this?
