otp_isochrone fails with rows >240

[jameswoodgeog]

Describe the bug
I am calculating isochrones for around 300 observations. When I run "otp_isochrone" with the "fromPlace" set to the sf object, the process fails. When I run the process in a loop to tackle each observation individually, the process is successful. Also, when I run the process on only the 1st n-rows up to a certain point (in this case 241 rows) it fails but 240 works.

To Reproduce
Using the IOW data in a local OTP server, the following code will reproduce the behviour.

Expected behavior
I expected all observation points to produce a multipolygon isochrone.

Additional context
@Robinlovelace as per the discussion this morning

[Robinlovelace]

Good to see the reprex @jameswoodgeog. Is it fully reproducible though? What's the test area and how did you set it up?

[jameswoodgeog]

Sorry, I forgot to mention. The above is reproducible. It is based on the IOW server and point data so I didn't have to provide my study area data.

[Robinlovelace]

OK great, will aim to give it a go. @mem48 any ideas?

[mem48]

@jameswoodgeog I can't reproduce this error, is this still a problem?
