A number of airnode PRs are failing on the E2E test step with the same error: Unable to find value at path: 'market_data.current_price.usd'.

Debugging (in-progress)

• Is the API responding. Yes.
• Is this specific to the E2E integration? No: the basic coingecko integration also fails with the same error for failing airnode-client-dev images
• Does completely rerunning (all steps, which includes building the images) previously successful CI runs cause CI failure? Yes. Example 1 - latest master commit. Example 2 - PR from a month ago.
• Does this error also occur for client gateway requests and not just client E2E with the local blockchain? Yes.
• Does this error occur for cloud deployments? No. Gateway and blockchain requests work (deployed airnode-deployer-dev CI passing and CI failing images on AWS).

The reason is axios/axios#5298 the response in the Airnode when run from a docker container looks like this:

Unfortunately, I had to add a log to print out the request response (we don't log this because there can be sensitive information). Not sure if we should not revisit this decision, because the logs are not helpful.

I see there is already a fix PR created so we can upgrade axios after that point... axios/axios#5306 not sure how this passed through CI though.

Hi @Siegrift , I assume this will be tested at the first completed PR, correct? Don't think we can test this from the user's perspective. I'll move this to Done if you give me an A-OK.

Since #1553 passed the tests we can consider this tested. Feel free to move to DONE.
